Firmware 1.19.1 on NUCLEO-WB55 is failing on BLE functions
Hello
MicroPython Firmware : 1.19.1
Board : STMicrolectronics NUCLEO-WB55
Since recent STMicroelectronics releases of stm32wb5x_BLE_HCILayer_fw.bin, available here :
https://github.com/STMicroelectronics/STM32CubeWB/tree/master/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x
all BLE scripts run on NUCLEO-WB55 boards are failing with message :
tl_ble_wait_resp: timeout.
Please help !
I did not found any way to restore BLE functions, even while downgrading stm32wb5x_BLE_HCILayer_fw.bin to rev 1.13 which was the one used for MicroPython firmware developement.
Best regards
Yannick
[NUCLEO_WB55 - USBDONGLE_WB55] disconnect usb
Hi all,
I have tried bluetooth demo from examples:
ble_simple_peripheral.py
ble_temperature.py
ble_uart_repl.py
on my devices (NUCLEO_WB55 and USBDONGLE_WB55) i have latest version og MP:
MicroPython v1.12-663-g9883d8e81 on 2020-08-05; NUCLEO-WB55 with STM32WB55RGV6
BLE stack firmware i have tried (V1.8.0) from STM32CubeWB
stm32wb5x_BLE_Stack_full_fw.bin
stm32wb5x_BLE_HCILayer_fw.bin
and in all tests usb devices was disconnected from pc, BLE example works correctly, i can connect to device and in case of ble_uart_repl.py repl work correctly.
is this the expected behavior?
Thanks,
D.
