An update to the instructions will be coming shortly. It should instead read:
If you’re ready to set up your Boron, follow these steps:
- You must have the Particle CLI (version 1.47.0 or newer) installed. Use
particle update-cli to upgrade if necessary.
- Put the Boron in DFU mode (blinking yellow) by holding down MODE. Tap RESET and continue to hold down MODE. The status LED will blink magenta (red and blue at the same time), then yellow. Release when it is blinking yellow.
- Update the device. If the device goes out of blinking yellow after the first command, put it back into DFU mode.
particle flash --usb tinker
When the command reports Flash success!, reset the Boron. It should go back into listening mode (blinking dark blue).
Create a program to set the APN and switch to an external SIM. Here’s the code. One way is to save this to a file, I called mine 3rdPartySIM.cpp.
(the rest of the instructions are the same)
