Bootloader STM_OTA update firmware and access to BLE characteristics via BLE and python script or other CLI

[PawelM]

Hi all,

I using Nucleo STM32WB55 and bootloader from STM (STM_OTA). For update firmware I using for now STM32CubeMonitor-RF and stm32WB USB DONGLE (which is part of nucleo kit). Now I would like to do this in other way - other tools, CLI, scripts...

Is some other tools to use to get access to BLE characteristics read/write and update firmware, some kind may CLI (STM32CubeMonitor-RF - i don't found any commands) or script in pyton or other laguage ?

I found BlueST-SDK but in my opinion don't work with nucleo STM32WB55 - I have issuess when try update firmware :

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