I am connecting qn9080 with Android using Web Bluetooth, and I am not able to send more than 20 Byte at a single packet. while if I connect using a Desktop browser I can send more than 20 Bytes.
I searched regarding this MTU exchange and I found "GattClient_ExchangeMtu()" API is there which will initiate MTU exchange. I called this GattClient_ExchangeMtu() from BleApp_ConnectionCallback() , But the GattClient_ExchangeMtu() is returning an error.
Can anybody help me on this to change the MTU size?
