Hello All,
We are trying to use nrf52810 with S112 soft device and 14.2 SDK.
We have problems with random disconnection with error number 8. This happens when central does not receive responses from peripheral.
We thought the problem was with the crystals or matching capacitors. But this does not seem to be the issue, we have tested with oscilloscope, the frequency is correct.
We are using the following crystals.
32.768 KHz - ST3215SB32768E0HPWBB
32 MHz - CX2016DB32000DPS
Still the problem is not going away. This problem occurs even with the example BLE Blinky program, which would normally point to hardware problems.
We are using connection parameters of 250/300ms, latency 5, and connection supervisory timeout of 6 seconds.
The behavior is also weird. When we use calculated matching Caps, the blinky has a higher rate of problem compared to our app. When we use a higher value, the blinky becomes more stable, but our app starts failing at a higher rate. I would have expected the blinky to behave better than our app in all cases, as it is a simple program.
Can you help us with solving this problem? This is a critical problem.
If we don't solve it we cannot make a product. And now time is also critical.
What information will help you debug it?
