hi,

Never succeeded to connect using hologram sim card the fw version is 02.06.A00.01, a tech from ublox send me an update to apply using EasyFlash, turned out that now the board is not responding anymore to any AT command, cannot power off the ublox using the button, cannot reset too using the button.

What’s next?

Try resetting via the manual linked here https://learn.sparkfun.com/tutorials/lt … ware-setup and doing the mentioned reset procedure; try a lower version of FW?

Do the LEDs flash @ power on?
