Weak connection during bluetooth throughput

[Sco]

Hi,

When I'm trying the throughput on nRF52840 with SDK v14.2, I set up a 52840PDK as a 'repeater'; in which case the 'repeater' will receive the output (20kBytes in total) from its peripheral (52840PDK) and then output to its central (52840PDK) through bluetooth. It shall hold both connection during the throughput process.

The firmware is proven working except sometimes when the peripheral outputs to the 'repeater', connection between the 'repeater' and its central will drop off.

Any idea why this would happen? Thanks!

Best,

Chenxu

Hi,

Do you get any error codes when this happens? Also you say this happens "sometimes", how often does this happen?

Hi,

I didn't see any error message from logger module.

I tried 20Kbytes and 2Kbytes throughput. The former may get around 5 times disonnection and connection before the data actually get through; while with smaller data size it happens less often, around once in 10 times.
