Some other LoRaWAN sensors, when work with Single Channel Gateway. we need to do some special configure like: Below set up instruction or [[Video Instruction to set End node to work in Single Frequency & Fix Data Rates>>url:https://www.youtube.com/watch?v=32eLnlYoLoI]] For a general LoRaWAN sensor, please see if similar setting (Set to work in single frequency and fix data rate) is possible. Otherwise, there will be problem for communication due to the limitation.
