Dragino LoRa shield as receiver

Hi!

I tried to made a receiver with Dragino LoRa shield. I'm using RadioHead library example of RH_RF95.h server. So my question is there a posobility to set frequency 864.1 MHz? And can I receive packet from comercial LoRa nodes or this is working only between two Dragino LoRa shields?

When I used it with wemos D1 mini and ESP-1ch-Gateway-v5.0--OLD I received package, but there was not stable work. I set node to 180 s to send a package, but receiving was't correct. Sometimes I get package after hour.

Sure you can set the frequency to 864.1Mhz, but only do this if its a 868Mhz band module. Details of the command to use are in the RadioHead library doccumentation.

If by 'comercial LoRa nodes' you mean LoRaWAN nodes, then yes you can receive the packets, but without all the keys and a lot of bother you wont be able to decode the payloads.

The ESP-1ch-Gateway, is not a TTN supported gateway and should not be used, it will disrupt traffic from other nodes.

Use a proper supported Gateway for reliable operation.

I know this!

I'm using this one MULTIGASSENS M2. I know all info about it, keys, frequency, power ... and how to decode the payloads. I have an instruction from manufacturer and software to change parameters.

Yes. I know this too.

I'm developing device with a lot of posobilities and I can't use just a gateway. I need only paylod from it and thats all.

Well if you know how to do it, why the questions ?

I have a question about frequency and can I receive packets. Thank You a lot for your help!

I can't get it work. I set parameters to node 864.1 MHz, SF12, 125 and 4/5 coding rate. My old ESP-1ch-Gateway can get packages from node. But dragino board can't. I am using just server code from library. I set frequency to 864.1 MHz. If I made it as client it works and my old 1ch-Gateway can get packages from dragino board. Any sugestions?

The RadioHead library does not provide a function to set the LoRa syncword and diffferent syncwords are used on LoRaWAN and non-LoRaWAN use cases.

Maybe You know some library or better code to receive packages from nodes with arduino uno and dragino lora shield?!
