How to access CRC? about bglib

[jrowberg]

There is no way to access CRC data at the API/BGScript layer. The controller hardware and host stack built in are designed so that any packet not passing a CRC check is rejected and never reaches the upper layers of the stack. I have never encountered a data integrity problem due to CRC issues with data flowing in either direction. In every case where unexpected data occurred, the problem was due to hardware serial transfer logic/voltage problems (e.g. UART clock mismatch) or buffer overflow (BLE1xx modules have only a 1-byte hardware FIFO).

Dear Jeff,
thank you for the clarification, I wasn't aware that it is handled on such a low level.
In this case, you are right, it must be a problem on the hardware, either on some serial transfer, or in my case even a SEU in cache/memory.
Best regards
Johannes
