Hi All,
I’ve two Bluetooth dongles and connected to two Linux systems(hostname1, hostname2). I’ve a test executable and it creates a BT link does the file transfer and calculates the throughput.
Are these dongle supports classic mode or Ble? Which profile are you using to establish connection between these two? ( PAN, ..etc)
I repeated the same test with the same BT dongles on another different Linux systems(hostname3, hostname4), here I’m getting less data rate.
After inserting dongles to host are you getting serial interface /dev/tty* or hci interface ? If its hci interface ,you can use hcidump to see packets and check MTU size
Here first I want to narrow down whether the issue is below device driver level or above device driver level and where the bottleneck is? which tools will help me to debug this kind of issue?
I think before jumping into driver level ,its better to ensure all bluetooth parameters are same on both the setups. Thanks, Hariprasad k
Thanks
