Downlink Messages intermittently being received by RN2903


(Jbcross) #1

I am having an issue not always receiving downlink messages on a RN2903 node. I am using a Multitech Conduit gateway, packet forwarding to the TTN server.

Sending messages from the node works every time. I am using the AU915_928 frequency band and I am wondering if anybody knows what value for RX1DROffset TTN uses (0,1,2 or 3)?

I have been told the RN2903 uses a value of 3 for RX1DROffset and I suspect TTN uses a value of 0. This means the receiving window data rate value on the node and TTN end will be different.

I have very good signal and do not believe it is a range issue

Hi, does your RN2903 works with AU channels? If yes, what firmware do you use? Thank you. Martin

Yes the RN2903 does work with AU channels. However you will have to contact Microchip Australia to get the correct firmware for the AU channels.
