advertising with s120

[mohBOSS]

Hi all,

Please I want to make sure of something. In the s120 specification, it's written " Bluetooth low energy combined Central and Peripheral SoftDevice", and even in the headers files, there is function for advertising (sd_ble_gap_adv_start()) . But when I try to use it, I get one of these errors NRF_ERROR_NOT_FOUND or NRF_ERROR_INVALID_STATE.

My question is : Does s120 support peripheral role or not. If not, how can I use a nRF51822 such as central and peripheral (alternatively).

Thank you !

Hi, The S120 support peripheral role, however, it's not concurrent with the central role like the S130. If you want to use the S120 with peripheral role you need to enable the softdevice with peripheral role (using sd_softdevice_enable()). Please have a look at sd_ble_enable() function in ble.h header file.
