Is it possible to bypass service discovery in S120 if UUIDs and characteristics of peripheral are known?

[boz]

Hi, I am using the S120 stack and wish to connect and control as quickly as possible to the peripheral. The central and peripheral devices are both embedded devices and are dedicated to each other for eternity. I only have control of the central source code. I have reduced the BLE_GAP_CP_MIN_CONN_INTVL_MAX to 30 msec. and it currently it takes about 1.5 seconds (that appears to be mostly discovery time) to accomplish this using the "ble central multilink" example. Is there way to shorten this time by bypassing the service discovery and just reading/writing the known characteristics directly? I don't think bonding is implemented/occuring but cannot be sure. It is not required. Thanks. Update: I have since learned that bonding will eliminate the need for service discovery, however, I do not think the peripheral I am connecting with is capable of bonding. I am not able to bond with it using the Master Control Panel.

Please have a look at this question.

Update: I can read/write the characteristics directly by not calling ble_db_discovery_on_ble_evt() from client_handling_ble_evt_handler() after connect, but the central/server is disconnecting prematurely. When using the ble_db_discovery_on_ble_evt() as intended it waits for disconnect from the peripheral/client normally (BLE_GAP_EVT_DISCONNECTED).
