I was delighted to receive my two new cores to complete the beehive monitoring project - but they don’t work.
The uFL core setup process goes through flashing blue, steady blue, flashing green and gets stuck there.
I have cleared wifi credentials, done a factory reset and tried setting the credentials by USB. I’ve confirmed that the credentials and wifi comms are good by reconnecting my old white core.
The power supply and router are fine and work reliably with my old core. I’ve tried two different routers (My usual TP link TD-W8968 and a TALKTALK D-Link DSL-3780 which both work fine with the old core) I’ve tried low and high gain antennae at different distances from the router. I’m in the UK so I’ve set the channel to a US compliant one.
The second new core has a chip antenna. This one breathes cyan as soon as I supply power. If I press the mode button it continues to breath cyan and I cannot get it into listening mode. I have done a factory reset and it goes through the expected sequence of yellow flash then white flash but then as soon as the mode button is released it is back to breathing cyan.
The troubleshooting guide doesn’t seem to cover this.
