gpiote problem

platform : nrf 52832 SDK : 14.0.0I used gpiote to detect sensor's interruption . there are two sensors ,so I configure the gpiote like this :void platform_gpio_int_initialize(){ if (!nrf_drv_gpiote_is_init()) { nrf_drv_gpiote_init(); } nrf_gpio_cfg_input(LIS_3DH_INT1_PIN, NRF_GPIO_PIN_NOPULL); nrf_gpio_cfg_input(LIS_6DS_INT1_PIN, NRF_GPIO_PIN_NOPULL); nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_HITOLO(false); in_config.pull = NRF_GPIO_PIN_PULLUP; nrf_drv_gpiote_in_init(LIS_6DS_INT1_PIN, ...

Hello,Nrf52832 ibeacon broadcast signal is unstable, and the rssi deviation of left and right upper and lower signals before and after the detection of the same distance is about 10-20. Is there any solution to stabilize the signal?Do you have a good antenna design recommendation?...

Hi everybody,I'm developing an product with :NRF52840, V0.9.0, SDK15In the DK I connected LIS3DH (accelerometer by TWI)all works.I configuration of HZ and temperature.even I can read the sensor. (the twi_handler works fine)but I included a code of NFC wake up (power on, sleep)and when the NFC wake up the MCU, I what to read again the accelerometer.in this moment the TWI RX or TX doesnt call the twi_handler. and the program stuck in while (m_xfer_done == false);I have tested disable Twi before to WFE, and ...
