My Sensors with Heltec V2

[dimoia]

Hello MySensors,
I have a problem.
I buy two Heltec Lora V2 and I wanto to use the first as Gateway and the second as node.

The gateway and relative node start (No FAIL detect) but, when the node try to send a msg the log print NO_REPY.

Ho I can find an example?.

Is possible to use Heltec as node and raspberry gateway with RFM95 ?.

thanks to all

Welcome to the forum @dimoia

I'm not sure if anyone has tried it, but the setup you are describing should work.

What spreading factor setting are you using for the lora modem? If you use the slow factors, you might need to adjust some timeouts. See https://github.com/mysensors/MySensors/issues/742

Are the devices withn range from eachother? ( at least 5m, but not many hundred meters away?)

Are you using the antenna that seems to be included in the kit? If not, what atenna are you using?

Hi Mikael,
I executed the instructions you posted and I solved the problem.
Thanks

Great work @dimoia, thanks for reporting back

Hello @dimoia ,
Trying to make a gateway and a node using the Heltec Lora Oled board, can you please post the settings you used to make it work with mysensors?
Thank you

@mrussi
Not sure if you still need this info, but I'll leave it here in case anyone else needs it. I couldn't find this either so i had to look at the heltec pinout diagram and compared to the ESP32 Library

 * The MySensors Arduino library handles the wireless radio link and protocol

 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.
