Hi Ryder,

To update the HL8548 you need to download the latest binary from the Source website.

https://source.sierrawireless.com/resources/airprime/software/hl8548-hl8548-g-hl8549-and-hl8549-g-firmware/

For each version you have 2 options. You can either use the Windows OneClickTool (exe) or the X-Modem version (.dwl).

1. OneClickTool - USB

Simply connect the HL8548 USB to your windows computer and run exe.

AS a pre-requisite you need to install the USB drivers:

2. OneClickTool - UART

similar to upgrade over USB but you need first to Configure the OneClickTool for UART download since by default it relies on USB.

To use the one-click tool to download over UART, you are required to create a HL85xx_download.ini file.
The .ini file specifies the COM port and baudrate
The file ‘HL85xx_download.ini’ must be placed in the folder path specified by %APPDATA%

The following example shows to use COM port 15 and set the baud rate to 460800 bps.
Even if your are using 115200 for AT command, you can set a higher speed for the download. 460800 is recommanded

File content:

[CommPort]
Port=COM15
ComBaud=460800

In case you are not familiar with %APPDATA% , this is a Windows environment variable.
To find it, just type %APPDATA% in the Start menu search section.
by default on Windows7 it’s the following folder:
C:\Users<user>\AppData\Roaming

3. X-Modem downlaod

You can use AT+WDSD command to load the binary in the module.
AT+WDSD=<size>

For the size you need to enter the exact size in Bytes of the xxx.dwl file. Accessible under widows with a right click in the File Explorer

Once you receive the NACK characters send the binary using 1k X-Modem protocol. A tool such as TeraTerm can be used for this task

At the end of the download you will receive a +WDSI: 3 indication

Send AT+WDSR=4 to launch the installation.

Wait for the module to restart.

You can refer to the AT command guide for more details:
