Heltec WiFi LoRa 32 V2/us915. Get stuck showing "Joining" #50

Open ztjona opened 2 years ago

ztjona commented 2 years ago

Hi I want to send some data using a Heltec WiFi LoRa 32 V2.

I follow the guide in: https://docs.helium.com/use-the-network/devices/development/heltec/wifi-lora-32-v2/arduino/

I have a hotspot that is in 1 floor above where I am testing the board.

I do not know why, but it can not join. I modified the build flags to show more info. This is the log I obtained.

I tried data rate 0 and 3: #define LORAWAN_DEFAULT_DATARATE DR_3

I also changed the mask to: uint16_t userChannelsMask[6] = {0xFF00, 0x0000, 0x0000, 0x0000, 0x0002, 0x0000};

Sometimes it also reboots, and I do not know why either.

Just to be sure, are you located in the proper region(US) you are trying to join on? Make sure to double check your devEUI, appEUI, and appKey.

The region is ok, my hotspot is US915 and it works fine in the helium network. The devEUI, appEUI, and appKey I just copied from a new device I created in Helium console. I double check it, it is fine.
