Chapter 4 – Examples

Example of a Master Discovery / Connection Sequence

From Power Up and No Connection:

1. Perform an Inquiry to obtain BT Address (unless it is already known).

Sent : ATUCL<cr> // Clears radio state and places in Idle Mode

Reply: <cr_lf>OK<cr_lf>

Sent : ATDI,1,00000000 {Class of Device}<cr> // Looks for only one Bluetooth device

Reply: <cr_lf>00A0961F2023,00000104,SocketWireless<cr_lf>

<cr_lf>DONE<cr_lf>

2. Perform a Master Connect over SPP using the BT Address.

Sent : ATDM, 00A0961F2023,1101<cr> // SPP connection

Reply: <cr_lf>CONNECT,00A0961F008F <cr_lf> // Returns Slave BT address radios is in Data

Mode

3. Place radio into Fast Data Mode.

Sent : ATMF<cr> // Places radio in Fast Data Mode

Reply:<cr_lf>OK<cr_lf>

4. Send Data.

Note: When sending commands from the Slave when the Slave connects in Fast Data Mode (ATSW25/or

issuing ATMF). All valid AT commands are sent through the Slaves UART will be interpreted and responded

by the Master radio as if it was the local Slave radio. Basically in this configuration from the Slave end you

can obtain status and configure from the remote Master radio. This is a unique feature that may be useful in

some applications but can confuse the user if you think you are talking to the local Slave UART.

Get Out of Data Mode and Check Status:

1. Delay at least 50 milliseconds; this could be less or more.

2. Get into Command Mode.

Sent : +++<cr> // Default escape sequence of characters

Reply:<cr_lf>OK<cr_lf>

3. Check Status

Sent : AT<cr>

Reply:<cr_lf>OK<cr_lf>

4. Or send any AT Command example:

Sent : ATSI,0<cr>
