HL8548 - firmware upgrade

Postby swissdotnet_sierra » Tue Jan 30, 2018 12:58 pm


I seek to update my sierra modem (HL8548) with the latest firmware and via XMODEM. Somebody has one documentation or tutorial to do this ?

I found nothing about this in official documentation, and I have read a misuse can broke the modem.

Thank you.

There is no Xmodem way to update a unit, the main way to update the unit through the UART is using the at+wdsd command which is detailed in the AT command manual.
