Quick connection parameters update

[Ziran]

Hello everyone,

I'm currently trying to change the connection parameters to be quick(100ms 0 slave latency) on a button press and after a timer timeout I go back to the low connection parameters.

I'm also sending a notification to an android application at the same time and then send back 2 characteristic ( LED toggle and a string for a LCD) .

It's working but it take quite a long time (10s) for my application to change the connection parameters so the 2 characteristic are not sent at quick connection parameters the first time but if I press a second time it's then updated and send it quickly.

Do you guys know a workaround this problem ?

Hi,

I encounter the same issue than Ziran. After the connection, I do a first update of the connection parameters to a standard rate, that is working well. Then I update the connection parameters to a fast rate but when I try to return in standard parameters, there is disconnection... Sometimes I succes to return in standard params, but this is working only once. I tried on Android v4.4.2 and v4.4.4 and that the same problem.

Is there a solution ? Thanks,
