I use a 52832 as the central device, a 52840 as the peripheral, the two established a connection for a period of time,(After a period of time (approximately 30s), there is no data between the peripheral and the central device to send or receive data from each other) the peripheral automatically disconnected, the reason for the disconnect is 0x16。
I also use my phone and peripherals to connect, which I haven't disconnected for a long time
The connection parameters for the host and peripherals are consistent, as shown in the following illustration
all use SDK15.0.0
Thanks for your query.
Could you please capture a sniffer trace when the issue occurs. That will make us observe if the issue is on the central side or in the peripheral side?
