Note! The RS9116 bootloader has the ability to load multiple firmware images, depending on the size of the images. It is not typical for multiple images to be required therefore, for the purposes of this documentation, image 0 is always used.

STEP 3. In the Tera Term menu select File -> Transfer -> Kermit -> Send... .

STEP 4. Navigate to the firmware image to be loaded.

Note! The latest firmware image is provided in the RS9116 WiSeConnect software package in the folder called .\RS9116.NB0.WC.GEN.OSI.x.x.x\firmware .

A progress bar appears during the transfer as shown in the following example.

STEP 5. Once the update is complete, the device prompts to enter another bootloader command. Press 1 to load the default firmware. The console displays Loading... followed by Loading Done as shown in the following example.

...

Loading...
Loading Done

Note! The bootloader automatically loads the default firmware after 20 seconds if a selection is not made beforehand.

STEP 6. Verify the new firmware version by typing the command at+rsi_fwversion? as shown below.

...

at+rsi_fwversion?
OK1610.1.2.24.0014

Note! Faster firmware upload speeds can be acheived by using the RS9116 EVK's USB-CDC interface instead of the UART interface.
