How change SubGHz_Phy_AT_Slave example for P2P LoraWAN

[Mihaita Ivascu]

Hello,

     I am running SubGHz_Phy_AT_Slave on STM32WL55JC1 board and I see when running AT commands menu that there are TX and RX tests. 

    I would like to use that example for peer to peer LoraWAN  between two STM32WL55JC1 boards meaning one sends 100 bytes using Radio and t he second one receives it and acknowledges but I am not sure how to modify that example.

     I have seen that there are suggestions about modifying some examples for using only Radio.Send and Radio.Recv for having peer to peer but not sure how it applied to this SubGHz_Phy_AT_Slave example.

    In that example I see that the TX and RX tests use some random generated payload(with Prbs9_generator)

    Has anyone used peer to peer Lorawan between 2 o boards successfully with the ST examples?

Thanks,

     Mihai

That doesn't make sense: LoRaWAN is, by definition, a "star" network - it is not peer-to-peer.

Do you mean just LoRa - not LoRaWAN ?

For that, see the "Ping-Pong" example ...

Or I should use the PingPong example and add there the AT commands code ?

Thanks,

So you do just want LoRa - not LoRaWAN - then?

If you want AT commands, then you will have to add them.

The example works without AT commands.

The example illustrates communication between two nodes using LoRa modulation - which is what you wanted?

Yes, I meant Lora. Sorry

Hello @Mihaita Ivascu 

As said TDK, for P2P communication, LoRa is what we are toking about. So, you may can use the SubGHz_Phy_PingPong and the STM32WL-SubGHz-PhyBasic-Tx-Rx. For the AT commands, you need to configure your own example based on the LoRa examples and you can refer to the LoRaWAN_AT_Slave just to know how to AT Command works.

Best Regards.
