Commands LORA: P-NUCLEO-LRWAN2

[pmendes03]

Hi, 

I recently bought a P-NUCLEO-LRWAN-2, and I would like to communicate through LORA from the gateway to the end-node and vice-versa, but some information is lacking.

In the Getting started with the P-NUCLEO-LRWAN2 and P-NUCLEO-LRWAN3​ starter packs DOC there is no inofrmation on how to send and receive data, for example, with the command LORA_send() I saw on a website, and the file USI WM-SG-SM-42 AT Command cannot be found, and the link given at [1] doesn't lead me anywhere.

Could you pls give me this information on how to receive and send data, or where can I see that Info. I don't need to use for now a dashboard, it would be enough to just put something on a terminal on one of the modules, and just see if the info was received on the other terminal, for example. 

I also know that the end-node has some sensores, how can I access them?

Thanks for your attention.

The USI product is evidently EOL

Hello @pmendes03 and welcome to the ST Community.

I suggest you to:

For the Gateway: I suggest you have a look at those videos.

For the End-Node: I suggest you debug the LoRaWAN_AT_Master and LoRaWAN_End_Node on the I-CUBE-LRWAN - LoRaWAN software expansion for STM32Cube - STMicroelectronics (the examples for the NUCLEO-L073RZ board).

Best Regards.

Not least because, as @Tesla DeLorean said, the USI module is obsolete. See this thread (yesterday):

That's really not what the Gateway is intended for - a Gateway forms part of a LoRaWAN Network, and expects to connect to & be controlled by a LoRaWAN Network Server:

If you just want to send stuff between devices, look at the peer-to-peer LoRa examples.

In the thread linked earlier, I gave a link back to an old thread on this.

As I recall, they are all ST sensors on I2C and/or SPI.

The schematic is in the GitHub repository linked from the other thread:

Thanks, I saw previous threads on this, but it was too late, I had alredy ordered it, so now I have to discover how to work with it :(

Thanks for this, I only used LORA so far, so this is a whole new concept for me

If you just want to send stuff between devices, look at the peer-to-peer LoRa examples.

About this peer-to-peer LORA examples, where can I find them?
