Does SoftDevice S130 V.2 have limitation in L2CAP_MTU size by 23 bytes?

Question

Hello, 
 I want to clarify one thing related to the limitaion in SoftDevice S130 V.1 of L2CAP_MTU size by 23 bytes. Is any way to extended it? 
 Because I see that changes BLE_L2CAP_MTU_DEF higher than 23 follows that sd_ble_l2cap_tx() function returns NRF_ERROR_NO_MEM error. 
 Does it mean Softdevice version 1 for nRF51 (in my case nRF51822) does not support it at all? 
 And the main question: If I switch my project to the newest SoftDevice version 2 will it help to have L2CAP_MTU size more than 23 bytes? Does it support already? 
 Thanks!

Unfortunately, neither of the S130 softdevices support or will support longer L2CAP_MTU size than 23 bytes. For longer MTU size, you will need to switch to nRF52832 and S132 v.3.0.0 or newer. 
 Update 20.03.2017: The sd_ble_l2cap_* API is a Nordic proprietary API. Using this API will only be for communication between two Nordic devices. 
 Each link layer packet is 27 bytes, where 23 bytes is data. It means that having more than 23 bytes of data per packet will only be of limited valued (because 27 is max). If a packet is longer than 27 bytes, it will be split into multiple packets.
