What controls do you use? Low power consumption BLE TBluetoothLE or ordinary TBluetoothManager?

CodePudding user response:

Bluetooth module is ordinary, mobile terminal should also is normal, today did not use the example code, debugging passed, but read write is an INTEGER, or no, arriving with a byte buffer to accept or 00.

Upstairs brother, can you solve it? Can the normal communication? Is how to solve? I also met the same problem with you

CodePudding user response:

There is no example, sharing and have a look

CodePudding user response:

This is usually not the problem of bluetooth, is the problem of data type conversion, see what you are using, for example, don't know where the problem is not code,

CodePudding user response:

XE7 bluetooth communication has a problem, also don't know is a tool itself a BUG or something better, suggest you use XE10, I used before
