On initial bootup, the module behaves as expected - passing all data transmitted to characteristic handle 0x11 to my serial terminal (see below)
Once I disconnect this terminal, the module re-enters API mode (see below)
This is happening even though I believe have disabled API mode in hardware by grounding the CYSPP pin. If I reconnect to the module, all data is now transmitted through the API mode UART interface (all data now encapsulated with "@E,...,D=data etc) which I would ideally like to avoid.
Would anyone please be able to let me know what is incorrect with my setup or thinking?
