All commands are issued from the local serial port side (PIC side) for the BT modules

BTM-182 (19200 initially):
	ATN=STN1110 OBDII       // sets the module's name
	ATQ1			// disable status reporting back to PIC
	ATL3			// set baud rate to 38400, match to PIC
	ATL5			// set baud rate to 115200, match to PIC
	turn local echo off...i think....need to test




HC-04 (EBAY module, 9600 initially):
	send just:  AT  should return "OK" (w/o pressing enter)
	AT+NAMEELM327_OBDII   <--- responds w/ "OKsetname"
	AT+BAUD6    <--- sets the baud rate to 38400
	AT+BAUD8    <--- sets the baud rate to 115200



RN-42:

$$$	// command mode
+	// echo on
S-,STN1110 OBDII   // make unique name appending last 4 hex digits of mac address 
SU,9600		// set UART baud rate to 9600 (to match STN1110 initial setting)
ST,30             //set remote access timer to 30 secs instead of 60
SA,1		// enable pairing password
SC,0008		// setup bluetooth CoD
SD,0500
SY,0004		// set radio TX power to highest setting
SI,0100		// set discovery/connect duty cycle to ~6% for additional power savings
SJ,0100
R,1		//reboot the module

.......now setup STN1110 stuff.....

then power cycle the module, connect to the device again and send the following:

STN1110 chip commands:
	STS@1 Designed by Andy Honecker 2011
	AT PP 0C SV 23      // set baud rate to 115200
	AT PP 0C ON	    // use new baud rate
	STSLXWT 50  // sleep input must be deasserted for 50ms before STN1110 wakes up
	STSLXP 0   // sleep is active low
	STSLXST 3000  //sleep must be asserted for 3 seconds to put STN1110 to sleep
	STSLX on, on   // enable sleeping and waking up

	STSLUIT 60  // go to sleep if uart is inactive for 60 secs
	STSLU on, on  // turn on uart triggering for sleep/wake
