- Infrastructure Mode
1. Configure the EVB in UART mode and connect a UART cable
4
between the PC
and the EVB. Switch SW4 and SW5 should be set to select the DB9 connector.
Configure an Access Point (AP) accordingly.
2. Supply power to the EVB and put on the power switch.
3. The message “Firmware upgrade (y/n)” comes in the screen. Press ‘n’ and then
“Enter” key immediately.
4. Once “Loading Done” message comes, the following commands should be
issued.
a. at+rsi_band=0
This configures the operating band of the module to 2.4 GHz. If a
RS9110-N-11-28-EVB, that is capable of operating over 5 GHz, is
used, a band value of 1 can be issued to configure the module at 5
GHz.
b. at+rsi_init
This initializes the module
3
It is assumed for illustrative purposes that the IP of the AP is 192.168.50.1

USB-to-UART converter cables are found to not work consistently. It is advised to
use a UART cable.
