Heltec WiFi LoRa 32 (V2) - Send / Receive

#1

Hi,

I bought 2 of these devices and tried the Example Lora Send and Receive code in Arduino.

I can see the 1 device sending data packets but not getting any updates on the receiver. Do I need to register the devices to use them ?

Sorry for the dumb questions but I am new to the Lora device.

Any help or examples would really good.

Cheers

Can you please try this example code? Both of your devices use the same firmware, and don’t forget to change the band to your working frequency.

Hi Thanks for your help, it worked a treat :grinning:

What’s the difference between the 2 bands ?

Thanks again.

Different countries and regions use different working bands:
