When initializing a UART instance (0 or 1 or both together), the current consumption increases to 600 μA
Then deinitialized UART, but consumption is not reduced!
- I tried not to use EasyDMA
- Tried nrf_drv_uart_rx_disable() before deinitialization
- Tried this: https://devzone.nordicsemi.com/f/nordic-q-a/15243/high-power-consumption-when-using-fpu
- Tried to reinitialize the pins after UART deinitialization
Nothing helps... =(
Code of UART deinit:
nrf_drv_uart_t* nrf_drv_uart_get_instance(uint8_t instance)
{
if(instance==nRF5x_UART0) return &nrf_drv_uart0;
return &nrf_drv_uart1;
}
uint8_t nRF5x_UART_deinit(uint8_t instance)
{
if(instance >= UART_INSTANCE_COUNT) return false;
if(nRF5x_UART_inited_flag[instance]) {
nrf_drv_uart_t uart = *nrf_drv_uart_get_instance(instance);
nrf_drv_uart_rx_disable(&uart);
nrf_drv_uart_uninit(&uart);
nRF5x_UART_inited_flag[instance] = 0;
}
return !nRF5x_UART_inited_flag[instance];
}
I always use __WFE() without SoftDevice and sd_app_evt_wait() with SoftDevice
SDK15 and S140 v.6.0.0 Production
