I had just bought it. It was all working fine, suddenly it lost connection and since then I'm unable to connect to Puck. I was working on some NRF/NFC related code. I tried resetting. The reset procedure completed successfully with red light blinking. But still, I'm not able to connect. Both my phone and PC is unable to discover the Puck during the scan. I also tried self-test by releasing button when all three LEDs are lit. It shows blinking green indicating all is well.
I tried resetting many times but still when I scan using MacBook or on my android phone, I can't find the Puck device.
And also, I'm not able to switch to bootloader mode. I tried pressing the button and released it just after I inserted the battery. Instead of red led, the green led is lit. How do I switch to bootloader mode?
Have I accidentally damaged the Puck? I don't think so because the self-test is working fine.
Thanks.
