I expierenced when setting channel while sleep mode it didn't changed
the channel inside the hardware registers. Then I got another report of
an user which has similar issues.
I increased the sleep to off state change timing, which is according
at86rf233 at maximum 1000 us. After this change I got no similar effects
again.
I tried another option to wait on AWAKE_END irq, which can be used to
wait until the transceiver is awaked. I tested it and the IRQ took 4
seconds after starting state change. I don't believe it takes 4 seconds
to go into the TRX_OFF state from SLEEP state. The alternative is to
increase the timings which seems to work.
Nicely spotted. Increasing the timing is fine here I think. Given the
datasheet actually assumes a maximum of 1000 us we should allow for it
as well.
Did you also check the maximum timing for 231 and 212 in the datasheet?
Just to make sure they are not different (for example higher).
