There are problems with IO in simpleBlePeripheral project

Other Parts Discussed in Thread: CC2541, BLE-STACK

I compile simpleBlePeripheral project and deploy it on cc2541 keyfob. All works fine, but i can’t switch off leds on P1_0, P1_1. How should I work with IO?

Can you show me how you do to switch off LEDs on P1.0 and P1.1?

I try to use function of hal led( HalLedSet( HAL_LED_1|HAL_LED_2, HAL_LED_MODE_OFF ) )) and set port's value ( P1_0 = 0; P1_1 = 0;). I did it in init and on timer every 1 second, but led is on always

There is a line "HalLedSet( (HAL_LED_1 | HAL_LED_2), HAL_LED_MODE_OFF );" in SimpleBLEPeripheral_Init(). If you set a breakpoint on its next line and debug to stop at it, are LED1 and LED2 still on?

After HalLedSet( (HAL_LED_1 | HAL_LED_2), HAL_LED_MODE_OFF ) led is on, after P1_0 = 0; P1_1 = 0; led is off, but then leds light up.

I just test on SimpleBLEPeripheral in BLE-STACK 1.4.1 using my KeyFob and I see no problem to turn off LED by HalLedSet( (HAL_LED_1 | HAL_LED_2), HAL_LED_MODE_OFF ). Do you modify anything on SimpleBLEPeripheral other than LED control using HalLedSet?

Thx. I update ble-stack to 1.4.1, and all works fine.

You are welcome and it is good to know it works for you now.
