Hi,
Can someone tell me if the Connection Event Min and Max lengths can be set in BlueZ? I have a customer using BlueZ and their throughput is less than optimal. It looks like from their sniffer logs that there is a single PDU sent every 18.75mS connection interval. Looking at the mgmt-api.txt doc in the BlueZ-5.64 release it doesn't seem the conn event length parameters can be changed.
New Connection Parameter Event
==============================
Event Code: 0x001c
Controller Index: <controller id>
Event Parameters: Store_Hint (1 Octet)
Param {
Address (6 Octets)
Address_Type (1 Octet)
Min_Connection_Interval (2 Octets)
Max_Connection_Interval (2 Octets)
Connection_Latency (2 Octets)
Supervision_Timeout (2 Octets)
}
This event indicates a new set of connection parameters from
a peripheral device.
The Store_Hint parameter indicates whether the host is expected
to store this information persistently or not.
Possible values for the Address_Type parameter:
0 Reserved (not in use)
1 LE Public
2 LE Random
The Min_Connection_Interval, Max_Connection_Interval,
Connection_Latency and Supervision_Timeout parameters are
encoded as described in Core 4.1 spec, Vol 2, 7.7.65.3.
I am a novice BlueZ user so if for one I am not looking in the right place please point me to where I should be looking for this info. And also if it is supported please could you provide details on how it can be supported.
Thank you in advance!
Chris
