How to disable RTS/CTS flow control in HostTestAPP project?

I am using CC2541 Mini Development Kits

How to disable RTS/CTS flow control in HostTestAPP project?

I find the code in C:\Texas Instruments\BLE-CC254x-1.3.2\Components\hal\target\CC2540EB\_hal_uart_dma.c

#define HAL_UART_Px_CTS 0x10 // Peripheral I/O Select for CTS flow control.
#define HAL_UART_Px_RTS 0x20 // Peripheral I/O Select for RTS must be manual.

if (DMA_PM || config->flowControl) {
UxUCR = UCR_FLOW | UCR_STOP; // 8 bits/char; no parity; 1 stop bit; stop bit hi.
PxSEL |= HAL_UART_Px_CTS; // Enable Peripheral control of CTS flow control on Px. }
else {
UxUCR = UCR_STOP; // 8 bits/char; no parity; 1 stop bit; stop bit hi. }

Does this code can disable the RTS/CTS ???

Yes, you can disable it by setting config->flowControl=false and make sure DMA_PM=0.

But I didn't saw where can I set the flowControl=false ??

Is it at C/C++ compiler -> preprocessor ,add in Defined Symbols ??

Try to revise "#define NPI_UART_FC TRUE" to "#define NPI_UART_FC FALSE" in npi.h.

Yes , I have do this.

I just want to know what the different between " DMA_PM=0" , "config->flowControl=false" and #define NPI_UART_FC FALSE" ?

In HostTestAPP, DMA_PM is set to 0 by default. After you define NPI_UART_FC to FALSE, the config->flowControl will be set to false in BLE stack and make flow control off.

I want to add PTM mode to keyfobdemo.

I reference the page of PTM Wiki:

http://processors.wiki.ti.com/index.php/PTM#How_to_Use_PTM_from_an_Application_Point_of_View

But I don't know where can I add the code of the following in keyfobdemo project???

1.Define the Pin

#include "hci.h" 
#define PTM 4 //Pin to use to check if Tester is connected 
#define RDY 5 
#define PDUP0 5 
#define P0ICON 0 
#define TESTER_CONNECTED() (P0_4==0)?TRUE:FALSE

2.set the RTS/CTS

void llSetupPTMTestPort( void ) 
{ 
　// ready UART0, Alternative 1 for the application to monitor 
　P0SEL &= (~BV(PTM) & ~BV(RDY)); // GPIO 
　P0DIR &= ~BV(PTM); // input; this is Tester's RTS 
　P0DIR |= BV(RDY); // output; this is Tester's CTS 
　P0 |= BV(RDY); // de-assert Tester's CTS 
　P0INP &= ~BV(PTM); // pull-up/pull-down depending on P2INP 
　P2INP &= ~BV(PDUP0); // pull-up 
　return; 
}

3.enable the PTM mode

llSetupPTMTestPort(); // check if Tester's RTS is asserted 
if ( TESTER_CONNECTED() ) 
{ 
　(void)osal_pwrmgr_task_state( task_id, PWRMGR_HOLD ); 
　HCI_EXT_EnablePTMCmd(); 
} else { 
　#ifdef POWER_SAVING 
　(void)osal_pwrmgr_task_state( task_id, PWRMGR_CONSERVE ); 
　#endif //Copy and Past the original init content here 
}

And the page of PTM-Wiki say it use the simpleBLEPeripheral.c , but I didn't saw the PTM code in

simpleBLEPeripheral project???

How to add the PTM mode in to keyfobdemo project??

Please verify the answer before raising another question.

So can flow control be disabled or not?
