First check if your gateway locally (or via ttn console) reports raw transmissions potentially related to these join requests.

Did you actually register your device with TTN?

yes
return command status Lora

Wake up .
GPS Init OK

but why did I receive the msg
FAIL The satellite signal cannot be found!

The RAK7200 doesn’t find GNSS (GPS, Glonass…) signals, that’s the reason for the “FAIL”.

Can you choose either this or the RAK forum - double posting causes all sorts of confusion.

I think Nikola’s response is probably the best course of action.

Hi @descartes the problem persists.
I believe my antenna and connector maybe not correct
I tested with different wait times over 100 but no improvement.
I am waiting for a new connector and a new antenna

Do you use an active GNSS-antenna? If you do, make sure that the powersupply for the antenna is switched “ON”

The RAK7200 is an all-in-one unit.

@envxcom, I post as nmcc on the RAK forum - I’ll be answering there, duplication of effort isn’t a good use of volunteers time and RAK are the subject matter expert on the RAK7200 …
