We are trying to use serial debug data from CY8CMBR2044. In the datasheet, a 41-byte packet is specified, however the chip is sending 71-byte data packets. Where can we find the specification for 71-byte packets? A 71-byte packet example:
0D 0A 00 03 0D EC 0D A9 0D A1 00 00 00 01 02 01 01 01 01 BB 36 34 34 11 08 08 0D EC 0D A9 0D A1
00 00 0B 00 0C 0C 0C 01 6C 68 68 00 20 00 00 08 B6 34 34 15 F4 01 00 00 27 29 29 80 01 01 01 89
1B 1A 9A 31 80 FF FF

The isuue was wrong baud rate. We measured it to be ~124600 (datasheet states 115200). After adjusting the baudrate on receiver side, we are now getting correct packets.

Hi
Can you please specify which specific 41 Bytes are you referring to?
Kind Regards
