Hang on LoRaWAN.joinOTAA(appEui, appKey, devEui); #20

Hi guys,

Just getting started with this core and im having a problem with the LoRaWANtest.ino for the grasshopper.

When i put in my keys and run the example it will hang on join. I have verified this with LED blinks.

Where in the code should i start digging to diagnose this? OR what am i missing?

Note that I am not actually using a grasshopper but the ST dev board. B-L072Z-LRWAN1. I have reconfigured the board to operate in standalone mode so it should work the same as a grasshopper.

Why not use the dev board variant?

" it should work the same as a grasshopper"

Nope...

Its what I was given to work with. The B-L072Z and the grasshopper both use the CMWX1ZZABZ module and have similar wiring so they should functionally work the same. PA8 is tied high for USB on this core. TCXO_OUT is tied to OSC_IN as per the grasshopper drawing.

VDD_TCXO is tied high on this board instead of OSC_OUT on the grasshopper. Could that be it?

I can get the MCU to function properly, serial, temps, etc. But comms with the SX chip just halt.

If you are using the L0 Arduino core from grumpyoldpizza just select the proper board variant for your board; it is not Grasshopper.

Otherwise it will not work.

I have resolved the issue.

kriswiner commented 5 years ago

How?
