Chapter 2 – AT Commands PARK Enable Park This command manually enables park mode for the device connected in time slots. Format: ATPARK,, Parameters: • Max Interval: Integer Value Time [ms] = Max Interval * 0.625ms • Min Interval: Integer Value Time [ms] = Min Interval * 0.625ms EXAMPLE: TYPE: ATPARK,1000,11 REPLY: OK OR NO CARRIER Notes: • Allow 7 seconds for the slave to drop its average current draw from 45mA to 3mA and go into PARK. Any UART traffic will cause the Slave radio go back to full operation within 5msec of the first character for 7 seconds before going back into PARK mode without subsequent data. The Slave will remain connected to the Master because the BlueRadios Module only supports one connection. • Both units are required to support park. Park request is sent from both Master and Slave to go into affect only during an active Bluetooth connection. The order does not matter. XPARK Exit Park This command tells the device to exit the park mode. Format: ATXPARK EXAMPLE: TYPE: ATXPARK REPLY: OK OR NO CARRIER Note: Unit will immediately exit park. RSSI and Link Quality Commands Golden Receive Power Range The lower threshold level of the Golden Receive Power Range corresponds to a receive power between -56 dBm and 6 dB above the actual sensitivity of the receiver. The upper threshold level is 20 dB above the lower threshold level to an accuracy of +/-6 dB. RSSI Get RSSI Value This command is used to obtain the RSSI value for an open connection on channel 0. This is a parameter associated with the ACL connection to a peer device. Format: Return Parameters: EXAMPLE: ATRSSI RSSI Value is in hex, typically from -10 to +31 in integer dB value. TYPE: REPLY: ATRSSI OK +00 OR ERROR Multi-Tech Systems, Inc. SocketWireless Bluetooth AT Commands (S000360G) 44
Chapter 2 – AT Commands Notes: • The RSSI value will be +00 if the signal is within the Golden Range. • The Golden Range min and max value is 1 and 12 respectively for the modules. • This value is the difference between the measured Received Signal Strength Indication (RSSI) and the limits of the Golden Receive Power Range (see below for definition). Any positive RSSI value returned by the Host side indicates how many dB the RSSI is above the upper limit. Any negative value indicates how many dB the RSSI is below the lower limit. A value of zero indicates that the RSSI is inside the Golden Receive Power Range. • How accurate the dB values will be depends on the Bluetooth hardware. The only requirements for the hardware are that the Bluetooth device is able to tell whether the RSSI is inside, above, or below the Golden Device Power Range. RSSIC Get RSSI Value by Channel This command gets the RSSI Value by channel number. Format: ATRSSIC, Parameters: Channel Number: 0, 1, 2, 3 Return Parameters: RSSI Value is in hex, typically from -10 to +31 in integer dB value. EXAMPLE: TYPE: ATRSSIC,1 REPLY: OK +00 OR ERROR LQ Get Link Quality This command gets the link quality of the current connection. Format: ATLQ Return Parameters: Hex value from 0 to 255 decimal, the measure of Bit Error Rate (BER) EXAMPLE: TYPE: ATLQ REPLY: OK FF OR ERROR Note: Link Quality is a Hex value from 0-255, which represents the quality of the link between two Bluetooth devices. The higher the value, the better the link quality is. Each Bluetooth module vendor will determine how to measure the link quality. In the case for CSR, this value is a measure of BER. LQC Get Link Quality by Channel This command gets the Link Quality by channel number. Format: ATLQC, Parameters: Channel Number: 0, 1, 2, 3 Return Parameters: Hex value from 0 to 255 decimal, the measure of Bit Error Rate (BER) EXAMPLE: TYPE: ATLQ,1 REPLY: OK FF OR ERROR Multi-Tech Systems, Inc.
