connection handle problem

[Anjaly]

hello, I am having some doubts regarding the connection handle. Will it be the same for both devices participating in a connection? I was trying to connect two devices, one as a peripheral and other as a central using S130 soft device. But in the central side it is showing the connection handle as zero!! And in the peripheral side as 3. I think connection handle zero is an invalid handle. But I could successfully do service discovery and characteristics writ using this handle. i am wondering how it happened!! But when I tried to disconnect using sd_ble_gap_disconnect(), it is showing error showing "Invalid param". What is happening here?? I could not figure out where I did mistake?? Can anybody please help me to solve this..

Thanks in advance

The connection handle is only used internally in the stack, so the connection handle in the peripheral has nothing to do with the connection handle in the central. They can however be equal, but that is just a coincidence.

The central will have connection handles from 0 to 7, the newer releases of the peripheral stack will have connection handle 0, while the older can have something else, like 3.

Connection handle 0 is not an invalid handle.

ok.. thanks for the reply. I figured out my mistake. the problem was with the parameters I gave in sd_ble_gap_disconnect().
