Switching from Legacy Binary Mode to AT-Command Mode#

The RS9116W legacy binary mode is no longer supported.

The steps below describe how to switch the RS9116W interface from legacy binary mode to AT-Command mode. For more details, see RS9116W Programming Reference Manuals.

STEP 1. Reset the RS9116 Evaluation Kit (EVK) by pressing the reset button or by power-cycling the board.

STEP 2. Enter the bootloader by pressing Shift + | followed by Shift + u; the bootloader menu is displayed.

BootLoader Version 1.0

1 Load Default Wireless Firmware
A Load Wireless Firmware (Image No : 0-f)
B Burn Wireless Firmware (Image No : 0-f)
5 Select Default Wireless Firmware (Image No : 0-f)
K Check Wireless Firmware Integrity (Image No : 0-f)
7 Enable GPIO Based Bypass Mode
8 Disable GPIO Based Bypass Mode
Q Update KEY
Z JTAG Selection

Note! The bootloader menu does not appear automatically on boot because the device waits to perform Auto Baud Rate Detection (ABRD). The character sequence Shift + | followed by Shift + u initiates ABRD causing the device to enter bootloader mode. For more details on ABRD and the bootloader, see the RS9116W Programming Reference Manuals.

STEP 3. To confirm the device is in legacy binary mode, try loading the firmware by pressing 1. If the device is in legacy binary mode, the console displays Loading... followed a garbled sequence of characters as shown in the example console output below (alternately, if the device is in AT-Command mode, the console displays Loading... followed by Loading Done).
