DA14695 and ext. Amplifier

I try to enable the TX_EN function on Pin P1_6 on the DA14695 Development Kit-USB without succses.

For this I modified the ble_range_dte project (WiRa_10.440.8.4) :

"main.c"

static void periph_init(void) { HW_GPIO_SET_PIN_FUNCTION(KEY1); HW_GPIO_PAD_LATCH_ENABLE(KEY1); HW_GPIO_PAD_LATCH_DISABLE(KEY1); #if EXT_AMPLIFIER // TX_EN hw_gpio_configure_pin(HW_GPIO_PORT_1, HW_GPIO_PIN_6, HW_GPIO_MODE_OUTPUT, HW_GPIO_FUNC_CMAC_DIAG0, false); hw_gpio_configure_pin_power(HW_GPIO_PORT_1, HW_GPIO_PIN_6, HW_GPIO_POWER_V33); hw_gpio_pad_latch_enable(HW_GPIO_PORT_1, HW_GPIO_PIN_6); hw_gpio_pad_latch_disable(HW_GPIO_PORT_1, HW_GPIO_PIN_6); #endif }

and in "ble_central_task.c"

void ble_central_task(void *params) { int8_t wdog_id; #if EXT_AMPLIFIER hw_sys_pd_com_enable(); hw_gpio_pad_latch_enable(HW_GPIO_PORT_1, HW_GPIO_PIN_6); #endif printf("Ble central DTE task\r\n"); ble_central_task_handle = OS_GET_CURRENT_TASK(); ...

The P1_6 is allways Low and if I use the P1_6 as an normal "HW_GPIO_FUNC_GPIO" then there is no problem to set and reset this pin.

Best Regards
