BlueSMiRF not going into idle mode

Wireless & IoT
1

I’m trying to interface the LCD development board for the MSP430F169 (http://www.sparkfun.com/commerce/produc … cts_id=772) with the BlueSMiRF bluetooth module. I’ve connected the two with the UART1 on the MPS430, and tried to send the BlueSMiRF into idle mode with the ATCLU\r command.

However, the BlueSMiRF doesn’t go into idle mode. I know that the UART is working, because I connected the RX and TX ports together and it receives fine. My code is below. I’m not sure what the problem is. Any help would be much appreciated.

Thanks!

unsigned char BTInit(void){

unsigned char *init = “ATUCL\r”;

// Pin configuration

P3DIR_bit.P3DIR_6 = 1; // Output (Transmit)

P3DIR_bit.P3DIR_7 = 0; // Input (Receive)

// Pin select

P3SEL_bit.P3SEL_6 = 1;

P3SEL_bit.P3SEL_7 = 1;

// UART init

U1CTL = SWRST + CHAR; // set SWRST and CHAR and clear everything else

ME2 |= UTXE1 | URXE1; // enable UART receive and transmit

U1RCTL = 0;

U1TCTL = 32; // use smclk

//IE2 |= UTXIE1 | URXIE1;

U1BR0 = 0x41; // 9600 baud, 8MHz clock

U1BR1 = 0x3;

U1CTL &= ~SWRST; // clear SWRST

// BT device init

while(*init){

while(!(IFG2 & UTXIFG1)); // wait for tx buffer to empty

U1TXBUF = *init;

init++;

// //Used to check TX RX on UART

// while(!(IFG2 & URXIFG1)); // wait for rx buf full

// LCDChrXY(0,0,U1RXBUF);

// LCDUpdate();

}

while(!(IFG2 & URXIFG1)); // wait for rx buf full

LCDChrXY(0,0,U1RXBUF);

LCDUpdate();

return 0;

}
