We are seeing an issue where the STM32WB55 module is failing to send a valid write response. The write response is attempted but based on the packet logs, the CRC is failing. This results in the central (app running on Android) forcing a disconnection. This always happens on the first connection to the module and is reproducible. We are using a very lightly modified version of the Cable replacement example. Pcap and project attached
