Can’t load defaults #15

ghost · 2020-06-24T09:20:25Z

Firstly thank you for such an awesome project.

I’m using the template sketch, and I set the load default config flag to true but I can’t seem to get it to work. No matter what I put in for the default data it doesn’t load it into the config portal. I tried eeprom clear hoping that would help and did double reset but also that didn’t work. What am I doing wrong?

You need to explain more clearly, with pictures, debug terminal outputs. It's difficult to guess what you're doing and where you're doing not correctly.

@thorathome is the author of the Blynk_WM_Template example. Please help.

Ok. I didn't ask my question correctly my apologies.

I'm using the Blynk WM Template example script that comes with the library in Arduino IDE. The portion of it that I can't figure out is this:

///////////////////////////////////////////////////////////////////////////////////////////
//// COMPILER SWITCH SELECTION - USE DEFAULT CONFIG PORTAL FIELD DATA OR NOT //////////////
//// SELECT IF YOU WANT CONFIG PORTAL FIELDS INITIALIZED TO SOMETHING OTHER THAN BLANK ////
//// This data only gets loaded on an initial compile and upload and after Config Portal data gets deleted
//// such as by using DRD (Double Reset) or the Blynk command Blynk.clearConfigData()
#define USE_DEFAULT_CONFIG_DATA true
//#define USE_DEFAULT_CONFIG_DATA false

I want to input into the code defaults like the Blynk Server, Blynk Server Port, Board Name, but no matter what I specify in the code like this it doesn't show up on the configuration portal fields. I've tried double reset, blynk.clearconfigdata(), recompiling, clearing eeprom, none of it works:

Are you using ESP8266 or ESP32, and EEPROM/SPIFFS or LittleFS?

ghost · 2020-06-25T20:41:09Z

Esp8266, littlefs

Please try New Blynk_WM v1.0.16 which fixes the USE_DEFAULT_CONFIG_DATA issue and let us know if it's OK.

ghost · 2020-06-26T08:28:02Z

Default settings are loading into the config portal now! Great.

However, it doesn't seem to program settings from portal onto device now. it shows in serial monitor that it's loading default values, not the values submitted on configuration portal.

The USE_DEFAULT_CONFIG_DATA has higher priority than Config Portal and it's designed for developers to test.
You have to turn that feature off in normal operation and Config Portal input data will take over.

//#define USE_DEFAULT_CONFIG_DATA true
#define USE_DEFAULT_CONFIG_DATA false

thorathome · 2020-06-26T17:19:55Z

Hi @khoih-prog

Thank you for the continued library development. I am building household control and monitoring apps with your library.

I am recompiling the Template sketch with the new library. Same code. (I did add a Blynk.clearConfigData() call to void setup().)
Same Default Config Data.
Having difficulty connecting with SSL

Any quick thoughts as I dig into this?
I do have new routers - Amazon Eero, but all my existing Blynk devices are working fine so far.

Thanks again and in advance.
Thor

THE CODE YOU KNOW

/*  
 * The Arduino/Blynk sketch Blynk_WiFiMgr_ESP32_8266_Template_HexColor.ino is a fully-developed 
 * get-started demo program for the powerful BlynkSimpleEsp... and the newer WiFiManager (WM) libraries. 
 * This demo sketch written by Thor Johnson (https://github.com/thorathome) May 2020 as a template for
 * Blynk Wifi ESP communications. See https://github.com/thorathome/Blynk_Examples
 * 
 * It demonstrates
 * * WiFiManager Config Portal configuration and use
 * * WiFiManager Dynamic (extended) Parameters configuration and use
 * * Use of compiler constants for compile-time selection
 * * Use of Blynk's BLYNK_WRITE_DEFAULT() flexible capability
 * * EEPROM and LittleFS (file system to replace depricated SPIFFS)
 *
 * This sketch lets end-users choose a color using ZeRGBa, colors a blinking (heartbeat) LED, 
 * and shows the HEX code for that color.
 *
 * This sketch requires:
 * * Blynk ZeRGBa configured in MERGE mode with values between 0 and 255
 * * Blynk LED
 * * Blynk Value Display
 * * Blynk master library installed
 * * Blynk_WiFiManager library installed
 * * ESP32 or ESP8266 device
 *
 * As in all Blynk sketches using WiFi, you will need
 * * Your WiFi SSID or SSIDs and passwords (I put mine in my library as a .h file)
 * * Your Blynk authcode or authcodes (I put mine in my library as a .h file)
 * * Your Blynk server URL (Main US Blyk server is blynk-cloud.com.)
 *
 * These values do not need to be coded into the sketch as they may be entered at runtime (once) 
 * into the Config Portal.
 *
 * You also do not have to hardcode the Virtual Pins for the ZeRGBa, LED or Value Display, 
 * can input them at runtime using the Config Portal. 
 * This sketch uses Blynk's BLYNK_WRITE_DEFAULT() capability to deliver this flexibility. 
 * I use this approach to manage a number of similar wireless controls like SONOFFs.
 *
 * The Config Portal will appear as SSID MyConfigPortal, with WiFi password of 12345678 
 * and IP address of 192,168,220,1. 
 * These three values (Config Portal SSID, password, IP address) are hardcoded into the sketch 
 * (but could be made selectable in the Config Portal, itself.)
 *
 * I hope this is as useful to you as it has been to me to understand Blynk, 
 * the BlynkSimpleEsp... and ...WiFiManager libraries, the ESP32 and ESP8266.

Having difficulty connecting with SSL
Any quick thoughts as I dig into this?

I have no problem at all connecting SSL (to my local Blynk Server) using ESP8266/ESP32.

But check that we have modified the USE_DEFAULT_CONFIG_DATA feature

The USE_DEFAULT_CONFIG_DATA has higher priority than Config Portal and it's designed for developers to test.
You have to turn that feature off in normal operation and Config Portal input data will take over.

//#define USE_DEFAULT_CONFIG_DATA true
#define USE_DEFAULT_CONFIG_DATA false

It seems that you might have either wrong tokens (taken from Default Config in sketch).

If you turn on USE_DEFAULT_CONFIG_DATA, you have to use the correct SSID/PW and BlynkServer/Token in your sketch as the board will use them.

After the first boot with USE_DEFAULT_CONFIG_DATA is ON, default Config Data will be saved in LittleFS / SPIFFS / EEPROM. You can then turn OFF USE_DEFAULT_CONFIG_DATA and let the board using the Credentials from LittleFS / SPIFFS / EEPROM as well as whenever you update from Config Portal.

It's a little bit confusing now, but I think this what you're expecting. Hopefully you will rewrite the README to explain more clearly to users.

 // This lets the Config Portal behave normally
  //#define CLEAR_CONFIG_DATA true  // DEBUGGING TOOL!  This deletes the device's existing Config Portal data in setup() 
                                    //    will force Config Portal up with DEFAULT_CONFIG_DATA [see code in void setup()]
  #define CLEAR_CONFIG_DATA false   // USE THIS FOR NORMAL OPERATION - use existing Config Portal Data as normal (provides continuity)

You don't need this feature now with new v1.0.16, necessary only if you're using v1.0.15
But good to have this option instead of using DRD.

Hi @khoih-prog

Thanks again for your time and patience. I made a #TrueNoobError with the new WM library loading. Forgot the certs file. Also had two copies of your library loaded up under Arduino IDE. My double bad. Fixed now for ESP8266&32.

All is Right With the World on a Friday.

I like your approach to LOAD_CONFIG_DATA, thanks. Easier to explain = primarily for development and debugging.

I've been saving up a few questions about using the WM Library

What is BOARD_NAME used for? It does not appear to be anywhere in the Config Portal data structure. Do we care? (I like DEVICE_HOST_NAME – shows up in the Config Portal and my router directory.)
How can I adjust the Config Portal to show only 1 SSID/Passwd or 1 Blynk server/authcode
(Where do I set [NUM_BLYNK_CREDENTIALS]?)
I understand the utility of
#define CONFIG_TIMEOUT_RETRYTIMES_BEFORE_RESET 3 // Library default is 10 (times 2) –
However, I am still unclear on what these two other #defines do and where should they be in my code?
#define TIMEOUT_RECONNECT_WIFI 10000L
#define RESET_IF_CONFIG_TIMEOUT true
I hate to ask, but do I need RTCwidget if I have SSL and am getting the time anyway?

I did find some bugs in the non-WM parts of my Blynk_WM_Template and will load the updated code.
Init, I removed the clearConfigData() code as it's no longer needed, also updated comments regarding USE_CONFIG_DATA.

Again, nice work. Thanks. I'm using WM.

@thorathome

Forgot the certs file.

That's why your README instructions is so important for everybody, even for the PRO like you.

What is BOARD_NAME used for? It does not appear to be anywhere in the Config Portal data structure. Do we care? (I like DEVICE_HOST_NAME – shows up in the Config Portal and my router directory.)

This is helpful for certain people in certain use case.

For example, you need 1 sketch for all boards, but thanks to personalized BOARD_NAME, you can differentiate the boards in running by personalizing a different BOARD_NAME for each board using Config Portal in runtime, then you can use BOARD_NAME for HOSTNAME so that on your Router, you can know which device is which. It's not nice that every board has the same name such as ESP8266_WM, ESP_XXXXXX, etc

How can I adjust the Config Portal to show only 1 SSID/Passwd or 1 Blynk server/authcode
(Where do I set [NUM_BLYNK_CREDENTIALS]?)

Not configurable now. You have to modify the library code, but not as simple as just modifying NUM_BLYNK_CREDENTIALS or NUM_WIFI_CREDENTIALS. If not use, you can specify duplicated or dummy data.

Will think about a simple way to do that, or just use 2 different source files for single set of Credentials.

Now making it simpler is not easy ;-(

I understand the utility of
#define CONFIG_TIMEOUT_RETRYTIMES_BEFORE_RESET 3 // Library default is 10 (times 2) –
However, I am still unclear on what these two other #defines do and where should they be in my code?
#define TIMEOUT_RECONNECT_WIFI 10000L

This is deprecated and is not used now after I used MultiWiFi features (from v1.07 or v1.0.11??), but forgot to delete. Need to clean house from time to time. No incentive and no memory at all until someone reminds !!! ;=}

#define RESET_IF_CONFIG_TIMEOUT true

If we're here but still in configuration_mode, permit running CONFIG_TIMEOUT_RETRYTIMES_BEFORE_RESET times before reset hardware to permit user another chance to enter Config Portal.

I hate to ask, but do I need RTCwidget if I have SSL and am getting the time anyway?

It's up to you. If you can manage time yourself using NTP in SSL, it's good. But not for everybody, especially in many cases, users don't use SSL. IMHO, using RTCWidget is preferable as it's much easier and simpler.

The USE_DEFAULT_CONFIG_DATA has higher priority than Config Portal and it's designed for developers to test.
You have to turn that feature off in normal operation and Config Portal input data will take over.
//#define USE_DEFAULT_CONFIG_DATA true
#define USE_DEFAULT_CONFIG_DATA false

Totally worked, thank you so much

To @thorathome and @kevinleberge

Your contributions are noted in Contributions and Thanks

Thanks to thorathome and kevinleberge to help locate the bugs, discuss the USE_DEFAULT_CONFIG_DATA solution leading to release v1.0.16. See Can’t load defaults and Setting "#define USE_DYNAMIC_PARAMETERS false" on Blynk_WM_Template.ino results in compile error

ghost · 2020-06-27T08:34:18Z

One last on this one. Either I'm not understanding it correctly, The Blynk VM Template description is wrong or it's not working as intended.

Currently it says:

///////////////////////////////////////////////////////////////////////////////////////////
//// COMPILER SWITCH SELECTION - USE DEFAULT CONFIG PORTAL FIELD DATA OR NOT //////////////
//// SELECT IF YOU WANT CONFIG PORTAL FIELDS INITIALIZED TO SOMETHING OTHER THAN BLANK ////
//// This data only gets loaded on an initial compile and upload and after Config Portal data gets deleted
//// such as by using DRD (Double Reset) or the Blynk command Blynk.clearConfigData()
#define USE_DEFAULT_CONFIG_DATA true
//#define USE_DEFAULT_CONFIG_DATA false

Maybe it should say
///////////////////////////////////////////////////////////////////////////////////////////
//// FOR DEBUG USE. IF YOU WANT TO FORCE CONFIG PORTAL FIELDS FOR TESTING ////
//// When this switch is on settings entered into sketch will be used regardless of what is entered into config portal ////
//// Set to false if you want to use config portal ////
#define USE_DEFAULT_CONFIG_DATA true
//#define USE_DEFAULT_CONFIG_DATA false

Hi @kevinleberge

Thanks for the help keeping this example up to date. Yes, you found a bug in the code. It is part of an even LARGER bug that I have now corrected and have posted on my own Github repository. I have also updated comments in the sketch, especially regarding USE_CONFIG_DATA, which has evolved considerably these past weeks.
All comments welcomed.

I've also submitted the same code to our benefactor @khoih-prog to post on his official Blynk_WM repository.

This is very helpful and much appreciated. Now that I have this code publicly available, I realize that I need to maintain it as the WM library evolves.

khoih-prog · 2020-06-27T20:22:04Z

Hi @kevinleberge

Just update Blynk_WM_Template to the latest version from @thorathome GitHub Repo.

Please have a look and test to see if there is anything not working as expected.
