We develope an USB Stick to connect some Bluetooth devices from us (with the same stack and the same Hardware).
Now it is on the market and some of our customers sometimes have problems opening the ports.
The function SPP_Open_Remote_Port returns RFCOMM_CONNECT_RESULT_CONNECTION_TIMEOUT
after 5 Sekonds. When we retry sometimes it works sometimes the same error come back.
Sometimes 3 attempts in a row fail this way.
That's why we have a lot of problems with customers.
What can we do, to make it better?
Helps an external antenna?
I use the last stack:
www.ti.com/.../CC256XM4BTBLESW
We use an LM4F232 to connect the CC256XB.
I start developement with SPP-Demo.
