LoRaWAN Library doesn´t work

#1

I’ve tried to use the LoRaWAN library that Heltec provides but I had some problems with it.

  • First, the guide is not updated. When you install the library, it doesn´t appear the option of choosing the Region in the Arduino tools menu. I think I resolve that changing this line of code:

/LoraWan region, select in arduino IDE tools/
LoRaMacRegion_t loraWanRegion = LORAMAC_REGION_EU868;

  • Second, once that you compile and upload the program, as soon an it tries to do the join, it reboots. I obtain this message:
ESP32 MCU init...
ESP32 MCU inited OK!

LoRaWAN EU868 Class C start!

joining...

Rebooting...
  • Third, everytime I compile the program I obtain this message that doesn´t stop the upload of the code, but I think that something is wrong:

Invalid version ‘Internal RTC2.0’ for library in: C:\Users\Dani\Documents\Arduino\libraries\ESP32_LoRaWAN-master

I am trying this with a Heltec WiFi LoRa 32 (V2), a RG1xx Laird Gateway and Chirpstack.

Can anyone help me? Thank you.

Maybe you need to download and update the latest LoRaWAN support environment from this. https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series.git

I already have the latest LoRaWAN support enviroment, so it is not the problem.

#4

Double click get.exe to install it?

I did it using the Arduino IDE, I tried downloading the repository as you have shown, and now it works, the program doesn´t crash anymore. I still have the third problem but I suppose that it doesn´t affect to the program.

Thank you very much :slight_smile:

Works for me too. In my case there was 2 boards with the same name.

Thanks.

You need to delete the old library.
