Indicates Bluetooth connection on Ch00. • PIO(3) Hard coded as input only. High signal of > 1ms will interrupt to wake-up CPU out of deep sleep mode if enabled. • PIO(4) Hard coded as input only. Triple Purpose PIO. Used for resetting factory defaults on power up and breaking out of Fast Data mode while Bluetooth connected. Also, if strobed, will auto connect to last paired or last connected device. • PIO(5) Hard coded as output only. Strobes to indicate slave or master inquiry in process. • PIO(6) User Definable. Defaults as input. • PIO(7) User Definable. Defaults as input. Can be used for flow control. Multi-Point PIO Functionality • PIO(2) Hard coded as output only. Indicates Bluetooth connection on Ch00. • PIO(3) Hard coded as input only. Defaults as input, high signal of > 1ms will interrupt to wake-up CPU out of deep sleep mode if enabled. • PIO(4) Hard coded as input only. Triple Purpose PIO. Used for resetting factory defaults on power up and breaking out of Fast Data mode while Bluetooth connected. Also, if strobed, will auto connect to last paired or last connected device. • PIO(5) Hard coded as output only.

Chapter 2 – AT Commands SW23 Write PIO Level This command sets the PIO logic level. Format: ATSW23,,, Parameters: ATSW23,,, • PIO#: 3,6,7 (6 & 7 not user controllable in MP mode, see notes above in ATSW22) • PIO State: 0 = Off (0V) 1 = On (+V) • Store: 0 = Do Not Store 1 = Store Parameters in Flash EXAMPLE: TYPE: ATSW23,6,1,1 REPLY: OK OR ERROR Read Using: ATSR21 SW24 Write Response, Security, Auto SCO, Filter Settings This command configures response, security, auto SCO, and filter settings. Format: ATSW24,,,, Parameters: > • Response Type (See Appendix B for more information): 0 = Long Response 1 = Short Response 2 = No Verbose Mode (No unsolicited responses will be output) No OKs will come back, but requested information such as ATSI, ATRSW, ATRSN and ATDI responses will. The device will not output CONNECT or DISCONNECT messages. In FTP and OPP modes the radio will still output all necessary messages such as PUSH START and PUSH COMPLETE. • Security: 56-bit encryption is automatically enabled when set to 1. UART will reply PAIRED, before the CONNECT, is returned when a connection is made. 0 = No Authorization 1 = Authorization Required Note: If security is enabled in multipoint mode, all connected slaves will have to use the same PIN. There is no way to assign an individual PIN to each slave. • Auto SCO: 0 = No Automatic SCO Connect 1 = SCO Auto Connect Upon Radio Connect. • Minor Filter: 0 = Disable Minor COD Filter on Inquiry 1 = Enable Minor COD Filter on Inquiry Note: With the minor filter enabled, inquiry results are filtered by the lower 2 bytes of the COD. If the minor filter is disabled all devices are found. Factory Default: Response Type = 0, Security = 0, Auto SCO = 0, Filter = 0 EXAMPLE: TYPE: ATSW24,0,0,0,0 REPLY: OK OR ERROR Read Using: ATSI,6 Notes: See Appendix B for differences between short and long response mode.
