typedef struct { uint8_t ch_37_off : 1; /**< Setting this bit to 1 will turn off advertising on channel 37 */

          uint8_t ch_38_off : 1;  /**< Setting this bit to 1 will turn off advertising on channel 38 */

          uint8_t ch_39_off : 1;  /**< Setting this bit to 1 will turn off advertising on channel 39 */

    } ble_gap_adv_ch_mask_t;

Comment says that "Setting this bit to 1 will turn off advertising on channel 37/38/39". Will it stop scanning too on the same channel ?

I am really confused. I want advertising and scanning on the fixed channels so that when device A is advertising on ch-37 the other device B will be scanning on ch-37. Also when device B is advertising on ch-38, device B will be scanning on ch-38. Is this possible to implement?

Hi,

Have a look at the BTLE_CHANNEL_MAP and how it is used, please refer to this github search result.

Hi Øyvind, Thanks for reply. I am not unable to map the needed behavior in the example you suggested. Where is the code for fixing channels to scan and observe?

Hi,

You can do this, have a look at the Advertiser observer example. It is based on a different SoftDevice and SDK, but the idea is still the same.

Best regards,
