I would try to increase the min and max conn interval instead, as this would give the phone more time to fit all the different connections. 10 ms is not that much when streaming audio. Other than that I have nothing else I can think of.

Thank you so mush Pal Haland.

I changed the connection interval to Min: 7.5ms Max: 10ms Connection supervisor timeout : 300

But this problem still exist.

Are there other suggestions?

Hi Kyu,

I see that you have set the

CONN_SUP_TIMEOUT = MSEC_TO_UNITS(300, UNIT_10_MS);

But this should in fact be at least (1 + Conn_Latency) * Conn_Interval_Max * 2 See Bluetooth Core 4.2 - Volume 2, Part E, 7.8.12.

The reason why it works on other phones might be how their controller select the connection interval to use.
