how to bt_disable in NCS2.0.x?

[yoyou]

Hello,

nRF5340+nRF21540, NCS2.0.2, vscode.

void go_system_off(void)

{

    printk("%s system off \n", CONFIG_BOARD);

    nrf_gpio_cfg_input(NRF_DT_GPIOS_TO_PSEL(DT_NODELABEL(button0), gpios),NRF_GPIO_PIN_PULLUP);

    nrf_gpio_cfg_sense_set(NRF_DT_GPIOS_TO_PSEL(DT_NODELABEL(button0), gpios),NRF_GPIO_PIN_SENSE_LOW);

 

    pm_state_force(0, &si);

    k_msleep(100);

}

void main(void)

{

    int err = bt_enable(NULL);

    if (err) {

        printk("Bluetooth init failed (err %d)\n", err);

        return;

    }

    err=bt_disable();// return  0xFFFFFF7A

    printk("hello world! %X\n",err);

    go_system_off();

}

sleep mode take 433uA,

if don't do  bt_enable(),  it take 20uA

why?

Hi,

Sorry for not getting back to you sooner.

CONFREG0
0x7D=1111101 (TX_GAIN=31, POUTA=20dB,TX=en)

when GPIO MODE , no connect  SPI to 21540,

how to write CONFREG0 to max power?

To write to CONFREG0 the a SPI connection is needed. With GPIO only the register cant be written to.

pins:

tx-en       set logic high,  enabled

rx-en       set logic low,   disabled

ant-sel     set logic low or connect to GND, use ANT1

mode       set logic low,   POUTA=20dB

above is means  (TX_GAIN=31, POUTA=20dB,TX=en,RX=disabed)  ?

Yes, this pin configuration will give 20dBm output power in TX mode.
