P1 is not able to connect to WiFi - Unable to receive key -19

[Dave]

Hi @dheerajdake,

So, if there was some issue that caused the local private key / flash to be corrupted, by say, a power issue, you might see this. I think we talked about it here:

P1 loses connectivity in safe mode - blinking cyan followed by 2 orange blinks and restart

Hi @dheerajdake, Good question! Usually some blinking orange indicates an issue with the handshake. The most frequent cause of this these days is some kind of corruption of the private key on the device. The flash can be corrupted if there is insufficient voltage or current to the device when it’s writing to the flash region. I would check to make sure your power supply / power circuits are able to support the minimum requirements for the P1. You should be able to restore the device using …

Please make sure your power supply is operating as required, then:

You can generate a new key for the p1:

particle keys new --protocol rsa

You can then use your JTAG pins to copy the device.der key to address 34.

Make sure you send the key to the cloud to unlock the pinned key with:

particle keys send YOUR_DEVICE_ID device.pub.pem

There are some docs around this here: https://docs.particle.io/support/troubleshooting/key-management/photon/

Feel free to send me your external IP address, and your device_id, and I can check the logs as well to see if there is any other information there.

edit: it's also possible the server key became corrupted somehow, so replacing that would also be a good thing to test.

Thanks,
David
