NUCLEO-WL55JC - no joined OTAA message and not joining the network.

Hi there,

I have a couple of these boards hooked up to TTN indoor gateway. However after swapping batteries one of them is not joining the network despite using the same files/firmware. Looking at the serial readout, I don't see the usual "Joined = OTAA", just the "MCPS-Confirm" loops, which look the same as the others.

Any ideas what could be happening?

Kind regards,

 

Oliver

Hello @ollyole and welcome to the ST Community.

I suggest you to :

  • Check the battery voltage
  • Check the antenna connection
  • Check the device ID and keys
  • Check the TTN gateway
  • Check for interference

I hope this is helpful for you
