STM32WB15 BLE_LLC_CHAT STACK ERROR

kiho_um · ‎2024-11-06

I am using BLE_LLD_CHAT APPICATION (ble_lld v.18) on 2 STM32WB15 SDK BOARDs and the following ERROR occurred.
The test condition is to use serial emulators on both ends and repeat transmission and reception at 1 second intervals.
The same condition occurs even after retesting.

[M0/SYS] ERROR: M0 can only manage one command !!

How can I solve this problem?

I was testing BLE_LLD_Chat (STM32CubeWB V1.20, stm32wb1x_BLE_LLD_fw v1.18) with 2SETs of "NUCLEO WB15 SDK" and the following error occurred.
[M0/SYS] M0 can only manage one command!!
After that, it stops.
The occurrence time of this state appears randomly.
The test conditions are given as an example in the figure.

Hello @kiho_um

Could you please give more details about your configuration. When you are having this message. Some screenshots may help. Also, could you try using the last Cube Package (STM32CubeWB).

Best Regards.
