33 / 51 page ![]() DocID023232 Rev 5 33/51 UM1547 FW configuration variables 51 Appendix A FW configuration variables The system configuration settings for each firmware version are given in the tables that follow. In order to set a configuration variable, enter “at+ab config xxxx = yyyy”, where “xxxx” is the variable name and “yyyy” is the value to set. A variable name could also be specified as “varzz”, where zz is the sequence number of the variable. Note: All changes require a reset to take effect. A.1 AT FW version 1.2 Table 9. AT version 1.2 system configuration settings – version 1.2 Variable Name Default Description Var01 BuildVersion xxxxxxx Date code software was built. Var03 BD_ADDR 00043e260e73 Bluetooth device address (Read-only). Var04 DeviceName Amp'ed Up! Code used for secure connection. Up to 20 characters are allowed (case sensitive). Var05 StreamingSerial True When true, hardware RTS/CTS flow control is disabled and data not able to be transmitted over the link will be discarded. When False, RST/CTS flow control is enabled. Var06 PIN 1234 Code used for pairing. Up to 16 characters are allowed (case sensitive). Var07 UartBaudrate 115200 Main UART baud rate: 1200 to 921,600 baud. Var08 UartParity None Main UART parity. Var09 UartDataBits 8 Main UART data bits per character. Var10 UartStopBits 1 Main UART number of stop bits. Var11 UartTimeout 44 Timeout used to determine the end of a message in units of bit times: from 8 to 128 are allowed. Var12 AutoSniff False This enables the sniff feature when the link is inactive automatically. Var13 AutoSniffTimeout 5 The inactivity timeout in seconds used for AutoSniff above. Var14 AutoSniffInterval 1000 Sniff Slot interval applied AutoSniff. Var15 HostDeepSleepEnable False Enables deep sleep mode. Var16 GPIO_HostKeepAwake None GPIO register used to prevent the module from entering deep sleep mode. A setting of none means that this function is disabled. Var17 GPIO_HostWakeup None GPIO register used to wake up the module after it enters deep sleep mode. A setting of none means that this function is disabled. |
