Connection Parameter Update during data xfer

[ran]

Hi, 

In my NRF52840 based application, I have a situation where the peripheral needs to pass 2K to central. 

In order to speed up the xfer, I'm requesting a Connection Parameter Update from the central ( which may or may not honor it ) . 

My question is as follows : 

Once the request to change conn param has been made, do I have to wait until I get PARAM_UPDATE from Master ? 

I mean wait before starting with data transmittion ? Or can I just go head and xmit and let conn update happen in the background  ?

Hi,

No, you would have to wait for the event as the central can reject it the connection parameter update.

I'm OK with the central rejecting it, the burst will take longer then. 

The question is if I can transfer data while there is a connection negotiation in the background ?

Hi,

ah sorry, I misunderstood the question. Yes you can continue with transfer of data while the negotiation is happening in the background. You don't have to wait for it to be approved or not before you can continue to send data.
