[Answer]-Flash program without Wifi Connection

Hey Guys,

Hope you are having a good day,

I am currently on a locked-down network, and cannot connect to the Particle Cloud. Therefore, I am trying to debug my connection issues, one of the methods of checking the network side is using a MAC Address. I know I can make a simple program to find a MAC Address but I cannot push that program to the Photon without a wifi connection.

If possible, I am trying to flash this program without Wifi, any suggestions?

Thank you,


Yes, via USB in DFU Mode

particle flash --usb <yourFirmwareFile.bin>

or in Listening Mode (less reliable)

particle flash --serial <yourFirmwareFile.bin>

(corrected, thanks @shiv for the heads up)
