Hello! Our KW45 Bluetooth side is the slave, and TI's CC2642 chip is the host. When the host is connected to KW45, it will hibernate after 60 seconds without any operation and turn off all RF signals of the host CC2642. However, the protocol stack on the KW45 side prompts disconnect until about 20 seconds after the host goes into sleep. It is not clear whether KW45 is in a virtual connection state during this time, and is there any way to improve this situation?
As shown in the figure below, it should actually prompt the detection of Bluetooth disconnection near 14:28:00:00, but the actual delay is 20s.
In the code to try to modify the air packet timeout parameter, the default is 10s, try to change to 3 seconds, but the phenomenon has not been improved, please tell me how to set the Bluetooth parameters?
Best Regards!
hello!
When we were connecting to Bluetooth, the Bluetooth slave did not send connection parameter updates to the host. We have repeatedly found that this situation occurs because the Bluetooth slave connection parameters have not been updated. How does the process of connecting parameters work in the protocol stack? Where can we modify it so that it can update the Bluetooth connection parameters of the slave machine.
