I’m testing the Arduino LoraWan_BMP280 example with a Laird RG1xx gateway and TTN.
It seems to work fairly well, except that the CubeCell PCB seems to miss a lot of the confirmation downlink packets, regardless of how close it is to the gateway.
Being fairly new to this LoraWan stuff, I’m trying to understand the sequence. Does TTN have to respond to the Laird gateway, which then sends the confirmation downlink message, or does the gateway respond immediately, without regard to the TTN link?
I ask this question because I’m wondering if it’s a timing issue, i.e. is the CubeCell closing the RX window too soon?
Thanks for any light anyone can shed.
