BLE_GAP_EVT_CONNECTED event timing question (nRF51822 w/ SDS)

[John]

Hi,

I am attempting to understand the timing of events when a mobile application connects to my nRF51822 based device. The reason being is that I have to enable the UART and establish communications with another micro controller before I can allow the central device to send commands to my application. I wanted to know if the BLE_GAP_EVT_CONNECTED event is sent up to my application right after the S110 SDS processes the connection request from the central device, or is is sent after the central device has read out all the services and characteristics, or at some other point in time?

Related to that, is there any time needed for the UART to be ready for use after I enable it?

Thanks, John

The connected event will occur right after the connection request have been sent on-air, as partially shown here.
