Make serial communication asynchronous

Question

Make serial communication asynchronous

Opened this issue 11 years ago · 2 comments

Currently, sending of data over serial is blocking the main thread. ~~The result is, that in case of a channel hop request, the packet handler state machine is blocked until the current serial transmission is complete.~~ (solve by moving hop logic inside packet handler ISR)

Implement serial TX as ISR, add isBusy() to UART that needs to be checked before reusing TX buffer.

non-critical with reworked packet handler ISR
