Datasheet need to be deeply studied to check this possibility. Wifi and bluetooth are great but probably overkill for such use... I'm investigating VDD dac conversion and writing down a protocol to send this info to the decoder. When ready I'll update the firmware.
If you rewrite the firmware for the transponder, for me it will be useful to have
the possibility to put the cpu in sleep mode port RA3 has a low level for some
seconds (may be 10s ) to save the battery and use an interrupt to wake up on rising edge. so when no movement, the transponder will sleep.
On the part of the decoder,
it could be useful to have an extended Cano mode, with three more bits on the
transponder number defined:
000b: Mylaps transponder type
001b: Club transponder type ( so no confusion when mixed with Mylaps
other: Reserved for future use.
