General issue report

Hello everyone,

I want to send data at a high data rate over BLE mesh. Theoretically, BLE mesh supports a data rate of 2 Mbps when using the 2M PHY. The practical rate is, of course, lower, but in my application, I can't even achieve a data rate of 1 kbps. The data packets with a size of 7 bytes are sent in the following loop with a delay of 10 ms, which corresponds to a data rate of approximately 0.7-1 kbps. (The transmission works with a delay of 100 ms and there is no error message)

Code Example:

uint8_t data[5] = {1, 2, 3, 4, 5};

for (int cycle = 0; cycle < 300; cycle++) {
    esp_ble_mesh_msg_ctx_t ctx = {0};
    ctx.net_idx = prov_key.net_idx;
    ctx.app_idx = prov_key.app_idx;
    ctx.addr = 0x00BE;
    ctx.send_ttl = 5;
    esp_ble_mesh_client_model_send_msg(vendor_client.model, &ctx, MODEL_OP_SEND, sizeof(data), data, 0, false, ROLE_NODE);
    vTaskDelay(10 / portTICK_PERIOD_MS);
}

Issue:

When sending 300 packets, I receive the error message after 256 packets: BLE_MESH: Out of network buffers. I have set the network buffers to the maximum value of 256 in the sdkconfig. This means that the network buffer is not being emptied quickly enough or the data is not being sent quickly enough. How can I configure my sdkconfig or code to achieve a higher data rate? What is the maximum transmission rate of the ESP32-C6?

Environment:

  • ESP-IDF version: v5.3 (also tested with v5.1.4)
  • ESP board: ESP32-C6-Dev-Kit-N8

Hi, @Florian-ger
Evaluating the BLE rate with BLE Mesh is not accurate because BLE Mesh by default retransmits a broadcast packet twice at 20-30ms intervals, which means a broadcast packet will take up about 60-90ms, which is also the reason why when you use 10ms interval to advertising the data, you will get the message BLE_MESH: Out of network buffers.

Hi @forx157,

Thank you for your response.

By retransmission of packets, do you mean the net_transmit setting in the configuration server? I have set the network retransmit count to 0 there. Additionally, I only send the packets to a unicast address (0x00BE, the server). Shouldn't it be quicker then?

I understand that achieving a transmission rate of 100 kbps is not possible, but I thought that sending packets would be much faster than a 100 ms delay.

@Florian-ger
I have tested it as you explained and there is no abnormality, can you share your test log with us after changing the log level of BLE Mesh to INFO level?

You can change the log level of BLE Mesh in menuconfig by following the path below:
(Top) → Component config → ESP BLE Mesh Support → BLE Mesh STACK DEBUG LOG LEVEL

If I set the BLE Mesh Stack Debug Log Level to Info, the program stops after 38 sent messages and does not print any further information on the serial monitor:

Hi, @Florian-ger
Since I can't reproduce your results on my end, I need to trouble you to do some more testing:
You can use the code in example/bluetooth/esp_ble_mesh/vendor_model to test if you can complete the advertising of 300 messages, if the test fails, please share the INFO level log with me.

Secondly can you easily tell me what you did in your test code? Or is there any way in which I can reproduce the problem you are having.

Hi @forx157 ,
Thank you for you help.
It works now with the vendor example. I don't know what was wrong with my code
