I have a batch of 10 or so Electrons that are not behaving as expected upon registration. Essentially, I am trying to set them up with a third party APN as outlined here. Most of them so far (about 20) have worked perfectly; however, the last several have been booting straight into listening mode (blinking blue) after uploading the new APN tinker script as downloaded from the official Particle installation process.
Any idea why? Some posts said it was due to bad positioning of the SIM, but that seems unlikely…I’ve re-sat them many times already with the same result.
