Re: [riot-devel] Counting retransmissions on at86rf2xx

Hi Oleg, probably there is a misunderstanding (I'm also not quite 100% sure at which end ;-) ) would not pass link-layer ACKs up to software in extended mode Hence, I was checking if the link-layer part (handling ACKs and taking care of retransmissions) might be already available in some

[riot-devel] Connecting RasPi with RIOT node via 6lowpan using ULAs

Hi, normally you can guess where the timer came from by looking at the address (or the debugger straight tells you). Is this somehow possible for your case (i.e. 0x200010a4)? That might be helpful for the timer people. Regards, Martine 2016-02-10 23:08 GMT+01:00 Michael Andersen

2016-02-10 Thread Andreas Weigel
Hi, if there is no code available, wouldn't it be rather easy to introduce a simple intermediate layer, set the number of retransmissions in the driver to 0, and re-initiate the transmission every time the driver reports a failure (up to the desired number of retransmissions) and count the
