I have a 7 imp002 which is mounted on PCB (have produced 100 of them - the others are sending data from concept test at customers). Now I’m trying to blink these 7 newly coated imp002’s. When I turn them on they’re just blinking “unsuccessful linkup”-code red blinking. Can’t contact them with the blinkup app - neither “clear config” or “new credentials” functionality. Something I’m not aware off? My last blinkup for devices was 1 month ago - maybe something new happend?
