AT Command Examples

The following AT command examples show how to operate the module in different modes.

Note!

All commands must be terminated with \r\n (CRLF).

Create an Access Point

This command sets the operating mode of the module.

at+rsi_band=0

This command sets the operating band of the module.

at+rsi_init

This command initializes the module.

at+rsi_ipconf=0,192.168.50.1,255.255.255.0,192.168.50.1

This command can be used optionally in this flow to configure the IP (192.168.50.1 in this example) of the AP.

If this command is not issued, a default IP of 192.168.100.76 will be used.

at+rsi_apconf=1,AP_SSID,2,2,12345678,300,2,4

This command will configure the SSID of the AP to AP_SSID and password will be set to 12345678.

at+rsi_join=AP_SSID,0,2

This command will create the Access Point with SSID AP_SSID.

A client device (Named Device A in this example) can now associate to the AP, open sockets and transfer data.

For example,

This command is used to set the user gain table. User can give input either in hex or decimal. For instance if the user intends to give input in decimal format, then the following procedure can be followed to run the Application using Docklight tool to provide input in decimal format.

Go to Docklight and provide sequence by double clicking on the left side provided send sequences column and enter the sequence normally up to init.
For at+rsi_gain_table command, Please enter the sequence normally in ASCII format, up to third parameter as shown in below figure.

Now for giving fourth Parameter i.e Payload ,user need to change the mode of the input either hex or decimal. In the screenshot decimal format is shown.
After the switching the mode to decimal, the input sequence will look like the following Figure.

Now from fourth parameter on wards, give the input in decimal format without any commas as the Application is expecting an array input(decimal) as shown in below figure.

After providing the payload of the gain table, the user has to again switch back to the ASCII format for providing \<CR> and \<LF>. Please follow the below figure. With this the gain_command sequence is successfully completed.

Once the sequence of commands and gain_table parameters are given properly, and executed the output will look like the below Figure.

Now from fourth parameter on wards, give the input in decimal format without any commas as the Application is expecting an array input(decimal) as shown in below figure.

After providing the payload of the gain table, the user has to again switch back to the ASCII format for providing \<CR> and \<LF>. Please follow the below figure. With this the gain_command sequence is successfully completed.

Wireless Firmware Upgradation Example in STA mode

The firmware of the module can be upgraded through web page. Execution:

Bring up the Silabs_STA using the following commands:

at+rsi_opermode=0,1,22,2147483648,2097152
at+rsi_band=0
at+rsi_init
at+rsi_scan=0,Silabs_AP

Give the IP address of the module in the browser(in this case 192.168.1.3), Redpine configuration page will be open.
Click on Administration.
Choose an .rps file from PC and click on upgrade.
After clicking upgrade button on webpage, module will send asynchronous notification

AT+RSI_FWUPREQ

Module has to issue the following command:

at+rsi_fwupok

If host has failed to give above command within specified timeout(~20 seconds), request will expire and upgradation process terminates.
After the firmware upgradation is successful, a popup message "Firmware Upgraded Successfully" will appear on webpage screen. And asynchronous success message AT+RSI_FWUPSUCCESS is send to host from the module.

Wireless Firmware Upgradation Example

The firmware of the module can be upgraded through web page. Sequence of events:

Start the Silicon labs device as an AP.
Allows stations to connect to update firmware through webpage.
A Laptop having WiFi card can be used as Wireless station.
Silicon Labs device creates a network and acts as router between the connected stations
Upgrade the received Firmware into the device.

Execution

Bring up the Silabs_AP using the following commands:

at+rsi_opermode=6,1,18, 2147483648,2097152
at+rsi_band=0
at+rsi_init
at+rsi_apconf=0,Silabs_AP,0,0,0,100,5,4

Note!

‘Authentication Required’ pop up window will only appear if BIT[23] in Custom feature bitmap is enabled. In that case opermode command should be at+rsi_opermode=6,1,18,2155872256,2097152\r\n Login credentials in case of ‘Authentication required’ : User Id : redpine password : admin

Connect to the Silabs_AP from a STA(in this example a laptop).

Open the AP configuration page by entering the IP address of the module in the browser.(in this case 192.168.100.76 by default).

Click on Administration.
Choose a .rps file and click on upgrade.

Upon clicking upgrade button on the webpage, host will get asynchronous notification

AT+RSI_FWUPREQ if it is connected to module through UART or USB-CDC interface.

So host has to issue the following command:

at+rsi_fwupok

If host failed to reply within specified timeout(~20 seconds), request will expire and upgradation process terminates.

After the firmware upgradation is successful, a popup will appear on remote peer screen to intimate the process completion . An asynchronous success message AT+RSI_FWUPSUCCESS is forwarded to the host connected with the module.

On firmware upgradation failure, there will be a pop-up on remote peer screen to intimate the process failure. Similarly, an asynchronous failure message AT+RSI_FWUPFAILED (for UART/USB-CDC) will be forwarded to the host connected with the module.

Note!

Wireless firmware upgradation is supported only for the latest versions of Firefox and Google Chrome.
When the user clicks on the upgrade button, the module starts erasing flash for storing image. This may take few seconds, after this, upgradation will start automatically.
After wireless firmware upgrade, the user needs to wait for few minutes (~ 1.5 minutes) after reboot so that the bootloader will copy upgraded image into the actual flash location.
Firmware upgrade will fail if server(module) does not receive packets from the client (browser) within the timeout i.e., 40 seconds.
Firmware upgradation failed message will be received if server/client closes the TCP connection.
Wireless firmware upgradation is possible in client mode also. Enter the IP address of the module in browser to land on configuration page.

Storing Configuration From User

This is an example sequence to store configuration from user.

at+rsi_opermode=0,1,4,0
at+rsi_band=1
at+rsi_init
at+rsi_usercfg=1294,payload in hex format>

Payload hex format

Above command configures module with the values set by the user. The values set here are:

Parameter	Value
`ssid`	silabs
`psk`	password
`opermode`	0
`feature_bit_map`	1
`tcp_ip_feature_bit_map`	4
`custom_feature_bit_map`	0
`band`	1
`cfg_enable`	1
`ip address`	192.168.1.2
`scan`	0 (scans all channels)

Note!

To configure more parameters, refer Store configuration structure parameters.
Parameters that are not required by the user can be configured as NULL values.

at+rsi_cfgenable=1

This command enables auto-join or auto-create on power up. To check the configured parameters give:

at+rsi_cfgget?

On power up, after bootloader options, immediately after the firmware is loaded you would receive OKC if the AP is available and the parameters are given correctly.

If you want to give new configuration, disable the current configuration using

at+rsi_cfgenable=0
