P-NUCLEO-WB55 - update firmware via BLE and read characteristic

[pawelm87]

Hi all

I have nucleo board with STM32WB55 chip with original bootloader from ST - STM_OTA. I can update program via bla using STM32CubeMonitor-RF and it's work fine for me. Now I would like to use Your script to load firmware via BLE and STM_OTA bootloader, but I have got some trouble.

In advertaising mode my device have name STM_OTA (the default ST bootlader) so I changed name of device :

IOT_DEVICE_NAME = 'TAI_110' -> IOT_DEVICE_NAME = 'STM_OTA'

after that I changed name of my bin file with new firmware:

FIRMWARE_FOLDER = '/home/ppawel/download/STM_OTA/'
FIRMWARE_EXTENSION = '.bin'
FIRMWARE_FILENAMES = ['test1'
]

After run script "example_ble_x.py" I used "user interfeis - terminal" to choose what I need - update firmware and which bin file, and after that the script crash:

~/Downloads/BlueSTSDK_Python/blue_st_examples $ sudo python3 example_ble_6.py

I have some question:

1. This script work/is compatible with this board (STM32WB55 and STM OTA bootloader) ??

2. How I can access to ble characteristic via scripts ??

Thanks for help for everyone
