I have got a Ruuvi tag for development purposes which I have opened and identified the following: 1) When powered on or if we press the Reset button, the LED blinks for 1-2 seconds. After that nothing happens. Is it expected? 2) I installed the Ruuvi station mobile app and tried to add tags but it was unable to discover.
Is there any way I can troubleshoot this or is there any way to do OTA firmware update to the tag?
I also verified using nRF connect mobile app to confirm that the ruuvi tag is not discovered.
