Hi All,

I am looking to update firmware on my HL7650 module using AT commands, but I don’t know where to start.

During my research, I found an document “AirPrime HL7 Series Firmware Download User Guide” being referenced in “Firmware 26.00.A01 Customer Release Note” ([https://source.sierrawireless.com/resources/airprime/software/release\_notes/airprime\_hl7650\_firmware\_26\_00\_a01\_customer\_release\_note/#sthash.Dz5o0F2b.dpbs](https://source.sierrawireless.com/resources/airprime/software/release_notes/airprime_hl7650_firmware_26_00_a01_customer_release_note/#sthash.Dz5o0F2b.dpbs))

However, I couldn’t find the actual pdf anywhere on sierra website, so I suspect it might be deleted? Does anyone has a copy of this document on their local machine?

If not, any documents or instructions regarding this issue will be much appreciated, cause I am only start working with HL7650 for the last few days.

Thank you in advance.

that document is not teaching you to download FW by AT commands.

You need to use at+wdsd= and then download by 1K XMODEM in tera term and then use at+wdsr=4 to install
