sequence 0 receiving¶
Ready to switch protocol!
Sending unknown bytes!
Read 12 bytes:
[0000] FE 00 FD 40 00 00 F1 B1 12 20 67 FC ........ ..g.
sequence 7,8 receiving, sending unknown string seq 01¶
Sending this string:
"\xfe\x00\xfd\x6f\x3a\x01\x00\x00\x00\x00\x34\xfc"
many times makes some other string appear on the serial port, sequence 7,8.
