23 hours ago radio.transmit() indeed does not work here - none of the (LoRaWAN) examples even mention this. node.sendReceive() is the way to go. But then I don't see your function loopThatAlsoNotWorks() being called, so it looks like your code doesn't even attempt this. Can you share what happens when you use this function instead?

22 hours ago Thank you for your quick response! Just to be sure I will send you the complete log; joinrequest and joinaccept i see in the log. But no uplink message. When i use my frequency analyzer i notice that the message actually been send by the device. I get "No downlink received", which probably makes sense as the message has not been received by Helium IOT. Hope you can advice me!

19 hours ago Are you in credit - ie you have pre-paid to be able to receive the uplink?

1 hour ago i have 196 data credits but I am not sure whether that is sufficient for uplinks. I wrote an email to Helium IOT about this issue. Thanks and i will keep you informed.
After a JoinRequest and JoinAccept I transmit "hello world". I see that via an rtl sdr that the message has actually been send; however I don't see the uplink message frame in my Helium-IoT Console. Note that transmit and sendReceive function do not result in an uplink frame. scanguard=50 and added enabled debugging; .
