S120 softdevice on nRF51822 : How to alternate between scanning and advertising

Question

Hi, 
 On a nRF51822 (QFAAG0) with S120 softdevice (using the recent PCA 10001 v2.2.0 board), i'm trying to perform these operations successively: 
 
 a simple RSSI scan 
 stop scanning 
 start advertising 
 
 Refering to this topic : Can nRF51822 support both central and peripheral roles? , it's apparently not possible, but why offering peripheral functions on S120 then, like sd_ble_gap_adv_data_set() , instead of on S110 only? 
 Unsure of that, i gave it a try (a bit stubborn). 
 Scanning works well, but i can't manage to initialize advertising data properly using
 sd_ble_gap_adv_data_set() function, using ble_advdata_set() from ble_advdata.h library, based on the board/pca10001/s110/ble_app_proximity example 
 I get the following error: NRF_ERROR_NOT_SUPPORTED 
 Before going further, i'd like to know if it's potentially possible to alternate between these 2 operations on S120 ?
If yes, is it possible to fill up the data field of the advertisement frame since it must contain the device name (referring to sd_ble_gap_adv_data_set notes) ? 
 Thanks in advance,
Arnaud

As the question you linked to says, it is not possible to use the S120 as a Peripheral, i.e. to advertise. The functions are included in the header files, but will as you have found out return NRF_ERROR_NOT_SUPPORTED. 
 Depending on your requirements, it could perhaps be an option to implement the scanner (or the advertiser, depending on which role you'll primarily use) in your application instead of using a softdevice. If you want to try this, you may have use in taking a look at this question .
