I am trying to develop a Payload Decoder for TTNV3 and TagoIO with RAK10701-P device, and @beegee is helping a lot (thank you), but the javascript that I received it has treatment for FPort =1 or FPort=2, but my device is sending FPort=3. Do you know what is the meaning for FPort=3? Take a look in the screenshot below
I take it back.
The Field Mapper can actually send with fPort 3.
fPort 3 is used in discovery mode, which I didn’t try yet. If I remember correct, it is used to create a map and will only work when disk91 backend is used.
It will send a bunch of packets quite quickly, then get a QR code from disk91 backend. The QR code will lead you to a website with a map of your position and the gateways/helium hotspots found.
