LoraWAN initialization fails in SX1276Read(REG_LR_VERSION)
wboerhout opened this issue · 4 comments
I have built the otaa_temperature_led example for Raspberry Pi Pico
Build goes fine, but executing, in main.c, lorawan_init_otaa fails. I added some debug code to lorawan.c, and I see that the failure occurs in the comparison "SX1276Read(REG_LR_VERSION) != 0x12"
As far as I can see, SX1276Read(REG_LR_VERSION) returns 0
Physical setup is a Waveshare SX127x module for Raspberry Pi Pico, I don't think pictures are necessary
Hi @wboerhout,
Do you have a link to the Waveshare SX127x you are using? Also, could you please describe the wiring you are using?
waveshare.com/wiki/Pico-LoRa-SX1262-868M
there is no wiring involved, the module is attached to the Pico using pre-soldered pins. see att picture, not much to see I'm afraid.
and the software came from https://github.com/siuwahzhong/lorawan-library-for-pico as directed by WaveShare
OK. I saw that the PIN layout was wrong, so I scratched the complete software tree and reloaded the ZIP file from https://www.waveshare.com/w/upload/0/08/Pico-LoRa-SX1262-868M_Code.zip
After building, the error was gone. It now loops in "joining the network" but that is for me to sort out. (network coverage, antenna, etc.)
