I am using a RAK811 with V2022 AS923 firmware flashed.
There are two types of packets my device will typically send, with different DR. The most common type of packet is sent with a DR of 3 (SF9BW125 for AS923). Therefore, the default DR of the RAK811 is set with "at+set_config=dr:3".
When sending the other type of packet, the following commands are sent:
"at+dr=5" (temporarily set to SF7BW125)
However, the temporary data rate is not being used consistently, as shown in the gateway log below. Sometimes, the default data rate of SF9BW125 is used instead.
I have not encountered other issues with the module. Is there anything else to check? Could there be a bug in the module firmware?
Edit: The RAK811 responds with "OK" to "at+dr=5".
