Hello. I’m trying to use the RAK3172 module with AT interface for a long range rural LoRaWAN application, but I can’t seem to figure out how to configure data rate = 0 on the AU915 band, it always returns AT Param Error. DR1 also fails. I really need the extra link budget provided by DR0 on this application, I saw a few other posts that recommended updating firmware but I’ve already updated to 4.1.1 and the error persists. Are there any modifications that I can do to the firmware to allow this configuration?
This is most likely linked to Uplink Dwell Time enabled:
I am not 100% sure, but I think this must be disabled on the LoRaWAN server.
Thanks for your response. I am using a RAK7268 gateway, latest firmware as well. But as my problem happens before the device talks to the LoRaWAN server, with the wrong DR setting most packets don’t even make it to the gateway at all, so no downlink is generated. I also am using exclusively ABP auth. I have devices from other manufacturers that work perfectly with the same gateway on DR0. Is there a way to change the Uplink Dwell Time on the RAK module itself so I can set it to DR0 via AT command?
When setting the DR, RUI3 checks whether UplinkDwellTime is active.
When using OTAA, dwell time enabled or disabled is set by the LNS. There is no command on the node (RUI3) to enable/disable the dwell time.
Not sure how it works in ABP mode.
