[Tinyos-help] tymo, senddone, error, fail, help

[De-MonHell]

hi all,

i know tymo is not considerable as stable yet, but:
 is it normal that sometimes sending a tymo packet, in the senddone event, 
return an error=FAIL also if the packet is correctly trasmitted? (the 
destination node received the packet for sure)
why does  it happens?

maybe tymo use a different codification for the error_t's enum?

thanks
