Hi Anjaly,

You can use sd_ble_l2cap_tx() to send and BLE_L2CAP_EVT_RX event to catch RX event. Doing this you can save 3 bytes (for ATT opcode, handle ID) in the L2CAP payload to transfer data. Please have a look at ble_l2cap.h

But you should be aware that you won't be able to use that to send data to a phone because it's your custom L2CAP channel.

Also, we are planing to change the APIs in S130 v2.0 (not to remove, but change) so you may need to update it when we come to the new S130 version.
