I looked at the Release Notes for the STM32WBxx Copro Wireless Binaries and kind of did everything according to the manual.
stm32wb5x_FUS_fw.bin -> 0x0809A000, tm32wb5x_Zigbee_FFD... -> 0x0804C000. However, after flashing the controller behaves unstable and sometimes shows FUS_ERROR, FUS_NOT_RUNNING. And after a repeated attempt to read FUS everything normalizes. Then I tried to use the example ZigBee_OnOff_Server_Coord, but nothing is transmitted via UART and there is no connection with the working Nucleo STM32WB55RGV6. The channels are set up correctly and I think it's ZigBee not working and I messed up something with the FUS. Also WB Commands are now unavailable to me.
According to the release note of STM32CubeWB package v1.18.0, see below the install address for STM32WB5xxG:
Subsequent attempts to read FUS normalize the situation, but the instability persists. Furthermore, when attempting to utilize the ZigBee example "ZigBee_OnOff_Server_Coord," there's a noticeable absence of data transmission via https://apkberg.com/ UART, and the expected connection with a functioning Nucleo STM32WB55RGV6 isn't established.
