RE: Delay data received at long ranges

Hello,

There may be several reasons for this. Your connection parameters are probably different when you are connected to an nRF52 and a phone.

My initial thought is that the packet length may differ between the two connections. If you are sending long packets, it means longer time on air, and a larger risk for noise and faulty CRCs.

Another possibility is that you may have different connection intervals on the phone and the nRF. Remember that it is the central that decides the connection interval, so even if you set the preferred connection interval on the peripheral, the central may choose something completely different.

Is it possible to capture a sniffer trace using the nRF Sniffer? Preferably a sniffer trace of both scenarios, phone and nRF52 as the central. If you can sniff the conection while you have the 5 second delay, perhaps it can reveal why it takes so long.

BR,

Edvin
