trying to connect to TTN V3, 2 days ago it worked (but not properly) at least I was able to send uplink messages which got decoded properly. Now it is not working. What I am asking myself: did I try to often and got “blacklisted” ?
I am doing a smart farming project where mkr1310 should be able to switched off and on as the farmer would use it just some months / year and where it controls irrigation, so the device would be mounted on one field for e.g. 2 nights and then on another. downlink would be timer settings and uplink would be status reports
