Serial debug data from CY8CMBR2044

[a72]

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

Hi

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

Hi, the format is described on page 11 in the datasheet: https://www.infineon.com/dgdl/Infineon-CY8CMBR2044_Four_Button_CapSense_Controller-DataSheet-v11_00-...

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.
