Is there anyone tried to use following setting able to deliver to border Gateway with success?

First of all, test success on sending message with eu868 and us915 from Sender using RadioLib, esp32 sx1262 as sender to waveshare/seeedstudio sx1302 hat(heltec sx1303 not working) as Border Gateway.

Then add one device act as Relay with seeedstudio sx1302 + pi4, same hardware as Border GateWay
Sender → Relay → Border GateWay

Then installed chirpstack-gateway-mesh + chirpstack-gateway-mesh-mqtt to both Relay and Border GateWay.

Then try to add a Relay with Add device to Border GateWay from Chirpstack web application, which is not able to add.

At the Relay tried to add application with a relay as device profile. Able to see packet coming and forward to Border Gateway, but packet not shown on Border Gateway.

Is there anyone have similar experience which able to share the setting example of Chirpstack web application on Relay and Border Gateway as reference?

Hi Hugo,

A few of us on this board have been trouble shooting the US915 mesh issue, and I think we are close to a root cause but do not have a solution yet.

I’ve detailed my finds so far in my thread here, it may help you understand why this fails in the US915 setup.

See also: Support transmitting using uplink frequencies (US915) · Issue #182 · chirpstack/chirpstack-concentratord · GitHub. I will fix this soon. As I have been testing this mainly using EU868 and 2.4GHz, this was something I overlooked.

Thanks Chris, currently we add a non LoraWan relay sx1262 device to detect if Lorawan gateway fail to reach, then pass the data with serial to sx1262 with two frequency of uplink and down-link for client project at the moment. I believe the main issue is that there will need to have screen captures tutorial for relay setup related from Chirpstack web interface for users. Our clients are in different countries. US915 not able to work at the moment. AS923 we are not able to make it too. EU868 ok, able to see the relay from Gateway. Just FYI for someone who is working in this area.
