STM32duinoBLE library does not work with the stock firmware that is loaded in the BLE module of STEVAL-MKSBOX1V1. For this reason, first of all, it is needed to solder on STEVAL-MKSBOX1V1 a JTAG/SWD 0.05" pitch 10pin male connector in the apposite space of the PCB.

Then you can use a standard ST-Link V2-1 with a JTAG/SWD 0.05" pitch 10pin to 20pin IDC cable together with STSW-BNRGFLASHER software tool (currently available only for Windows PC) in order to update the firmware of the BLE module of STEVAL-MKSBOX1V1.
First of all, install the ST BlueNRG-1_2 Flasher Utility and open it, then select the SWD tab:
[[/img/stm32duinoBLE/SensorTile_Box2.PNG|alt="SWD tab of ST BlueNRG-1_2 Flasher Utility"]]
Erase the flash memory of the BlueNRG-1 chip:

Download the archive STEVAL-MKSBOX1V1.zip that contains the Link Layer Only firmware named DTM_LLOnly.bin for the BLE module.
Load the Link Layer Only firmware in the ST BlueNRG-1_2 Flasher Utility and then press the "Flash" button:

If you need to restore the stock firmware of the BLE module of STEVAL-MKSBOX1V1, you can repeat the procedure using the firmware image DTM_Full.bin included in the same archive STEVAL-MKSBOX1V1.zip.
STM32duinoBLE library could not work with the stock firmware that is loaded in the BLE module of X-NUCLEO-BNRG2A1 expansion board.
For this reason, first of all, it is needed to solder on X-NUCLEO-BNRG2A1, if it is not soldered, a 0 Ohm resistor at R117.
Then you can use a standard ST-Link V2-1 with 5 jumper wires female-female together with RF-Flasher Utility software tool (currently available only for Windows PC) in order to update the firmware of the BLE module of X-NUCLEO-BNRG2A1.
You need to connect the J12 pins of the X-NUCLEO-BNRG2A1 to the pins of the ST-Link V2-1 as shown in the picture below.
[[/img/stm32duinoBLE/X_NUCLEO_BNRG2A1_1.PNG|alt="Connection among the J12 pins of the X-NUCLEO-BNRG2A1 and the ST-Link V2-1"]]
In particular we have the following connections:
| J12 | ST-Link V2-1 | |
|---|---|---|
| Pin | 1 | 1 |
| Pin | 2 | 9 |
| Pin | 3 | 12 |
| Pin | 4 | 7 |
| Pin | 5 | 15 |
First of all, install the RF-Flasher Utility and open it, then select the SWD tab:
[[/img/stm32duinoBLE/X_NUCLEO_BNRG2A1_5.PNG|alt="SWD tab of RF-Flasher Utility"]]
Erase the flash memory of the BlueNRG-2 chip:
[[/img/stm32duinoBLE/X_NUCLEO_BNRG2A1_6.PNG|alt="Erase of the BlueNRG-2 chip"]]
Download the archive X-NUCLEO-BNRG2A1.zip that contains a new version of the firmware for the BLE module name LUENRG-M2SP_DTM_SPI.hex.
Load the new firmware in the RF-Flasher Utility and then press the "Flash" button:
[[/img/stm32duinoBLE/X_NUCLEO_BNRG2A1_7.PNG|alt="Load and flash the new firmware into BlueNRG-2 chip"]]
If you should find some issues during the update process, you can try to repeat the procedure closing the J15 jumper on the X-NUCLEO-BNRG2A1 expansion board.
