Hello fellow developers,
We are currently working on debugging an issue with one of our lora devices that is supposed to operate in US915 region. We are using using LoraMac 1.0.3 on the device and TTIG gateway for US915. The issue is that the device is not capable of joining/finding the gateway for many retries. The device is able to find the gateway and join the network when it tries channel 9 and DR 4, otherwise the gateway is not picking any uplinks. After joining the network the device is still not able to send uplinks. It manage to send uplinks to the gateway but doesnt get any response.
Personally I don’t want to mess too much with the LoraMac library and trying to debug the device itself and the gateway. Has anyone have had similar problem or could provide any tips on where to check?
Gateway does not pick any uplinks except when the device joins on channel 9 and DR 4. Once in network, the device is able to send uplinks but do not receive any downlinks from the gateway.
