Hi @Akshay

Hope you are doing well! Are you able to solve this nrf21540 with nrf5 SDK?

Thanks in Advance!

Hi,

The Softdevice doesn't support the driver yet. It's meant to be used with the more lower level application such as radio test etc.

hi,

i used that driver nrf21540.c and .h from radio test example and i used those files in ble perepheral / ble_blinky example. i called the functions from nrf21540.c file like this in main()

int main(void)
{
// Initialize.
log_init();
// leds_init();
timers_init();
// buttons_init();

nrf21540_init();
nrf21540_ant_set(NRF21540_ANT1);
nrf21540_pwr_mode_set(NRF21540_PWR_MODE_A);
nrf21540_tx_set(NRF21540_EXECUTE_NOW,NRF21540_EXEC_MODE_NON_BLOCKING);

power_management_init();
ble_stack_init();
gap_params_init();
gatt_init();
services_init();
advertising_init();
conn_params_init();

// Start execution.
NRF_LOG_INFO("Blinky example started.");
advertising_start();

// Enter main loop.
for (;;)
{
idle_state_handle();
}
}

but when i call the nrf21540_tx_set(); the code is not advertising.

or should i call this nrf21540_tx_set & nrf21540_rx_set in any radio events

this is my pin map

#define NRF21540_RXEN_PIN NRF_GPIO_PIN_MAP(1,13)
#define NRF21540_TXEN_PIN NRF_GPIO_PIN_MAP(1,10)
#define NRF21540_PDN_PIN NRF_GPIO_PIN_MAP(1,02)
#define NRF21540_MODE_PIN NRF_GPIO_PIN_MAP(0,29)
#define NRF21540_ANTSEL_PIN NRF_GPIO_PIN_MAP(0,02)
#define NRF21540_CS_PIN NRF_GPIO_PIN_MAP(1,04)
#define NRF21540_MOSI_PIN NRF_GPIO_PIN_MAP(0,25)
#define NRF21540_MISO_PIN NRF_GPIO_PIN_MAP(1,06)
#define NRF21540_CLK_PIN NRF_GPIO_PIN_MAP(0,24)

where to call those tx and rx set function

im using gpio not spi

pls reply

Hi,

There is planned future support in NCS, for now there is a driver in nRF5SDK at \driver_ext\nrf21540\

No spi example is available yet. The DTM and Radio test example supports the nRF21540.

[quote user="Akshay19"]what that radio test example do[/quote]

Read the documentation.

i found a radio test example(pca10112) in sdk. how can i use this to implement that in our application code. and what that radio test example do
