Hi all
I want to know the difference about the data transfer between

andQLowEnergyBluetooth
.I found I can connect my device with
QLowEnergyBluetooth
but I can't use these service uuid to connect withQBluetoothSocket
, like this device as follow:"Generic Attribute" characteristic count 0 "Unknown Service" characteristic count 2 characteristic name "" description count 1 descriptor name "Client Characteristic Configuration" characteristic name "" description count 0 "Generic Access" characteristic count 4 characteristic name "GAP Device Name" description count 0 characteristic name "GAP Appearance" description count 0 characteristic name "GAP Peripheral Preferred Connection Parameters" description count 0 characteristic name "" description count 0 "Unknown Service" characteristic count 1 characteristic name "" description count 1 descriptor name "Client Characteristic Configuration" "Device Information" characteristic count 3 characteristic name "Model Number String" description count 0 characteristic name "Serial Number String" description count 0 characteristic name "Firmware Revision String" description count 0
#Using QBluetoothSocket qt.bluetooth.bluez: SDP scan failure QProcess::ExitStatus(NormalExit) 126 qt.bluetooth.bluez: SDP search failed for "F1:11:38:FE:CB:1E"
I want to read/write data between the device and my program, what should I do?
