Here the procedure :

 - Join -> Join OK

 - Uplink , a downlink is send by the network

at this point sometimes (near 25%), no more uplink is send after.

I did not success to reproduce this problem in debug mode to understand what the problem is.... :(

Is someone already see this problem ?

i am using the i cube lrwan v 1.1.0 software.

Ok now i understand all the problem that i have on the I Cube LrWan 1.1.0

It is based on a fork of the semtech develop branch (date end of february) !!!!

THe previous version 1.0.3 of the I Cube lrwan library seems more stable (as based on a official version of the  master branch, the v 4.3.0)......

Very strange to make a fork of the dev branch of the middle of a development !

SO this problem does not appear with the v1.0.3.

I don't understand how you say that your library is ok for the V1.0.2 of the specification, as the semtech stack for this specification is not yet finish....
