Hello, i'am trying to implement a CRC calculation in AI2. But i dont get the expected result and want to ask if there is an obvious Error here is the C-Code on the BLE Device: for (uint8_t i = 0; i < 5 ; i++) { // CRC Check of Header (CMD, Adress, Size crc = _crc_xmodem_update (crc, …

I want to post my Solution for the CRC Calculation. A second error appeared with larger lists. The CRC Value has to be 16Bit (uint16_t). If not the CRC Value get bigger and bigger until it doesn't work anymore and the crc is wrong. [AI2_CRC_OK1] [AI2_CRC_OK2]
