[deepu]

hello, In order to develop a project on master-bridge-slave,i found scan_start() in the ble_central program.But the function definition for sd_ble_gap_scan_start() in scan_start() is not to be seen.where can it be found??Is it because it is written in OS it is not seen??

  Please be kind enough to help me.

regards

in ble_gap.h which is included when you include ble.h

[deepu]

that is the declaration of the function,no definition

[RK]

It's both declaration and definition

SVCALL(SD_BLE_GAP_SCAN_START, uint32_t, sd_ble_gap_scan_start(ble_gap_scan_params_t const *p_scan_params));

provides the code which executes the service call into the softdevice.

Hi,

You won't be able to see exactly what's going on inside sd_ble_gap_scan_start(). All functions prefixed with "sd_" is a part of the SoftDevice which is Nordic's proprietary Bluetooth protocol stack solution. To learn more about the SoftDevice you can read the SoftDevice Specifications found here. There is also some documentation of the functions here.
