You can use the github.com/.../nRF51-multi-role-conn-observer-advertiser and setup an advertiser that uses only one of the channels. Use the API call

void btle_hci_adv_params_set(btle_cmd_param_le_write_advertising_parameters_t* adv_params);

and set the btle_dd_channel_map_t to the channels that you want to use. This will enable you to use the advertising channels of your choice.
