Hello,
I followed this how-to (https://wiki.seeedstudio.com/Build-LoRaWAN-Sensors-SenseCAP-XIAO-Controller-Data-Logger/) to connect my scd41 sensor, my sensecap S2110 and my S2100 datalogger.
I connected that on my Lora service. I received lora data messages.
First issue : all my measurements are at 0 in the SenseCAP APP. I don’t know why. I followed very precisely the how-to et checked a lot of times.
Second issue : I receive 2 data messages
Why? Which message receives the correct sensor values? the first or second one ?
Third issue : What decoder do I have to use in the wiki? Github. Here the two lora data messages.
