some thoughts: the message queue is using a lot of critical sections.
if you don't need to send messages from an interrupt handler, I would
advise to write a new version which doesn't use any critical sections
(which are bad for bt uart..:)
does anybody NEED to send msgs from an IRQ handler?
right now, msg.c also uses periodic timer which are not implemented well
in terms of interrupt latency. this is something being currently worked
