I’m using Python with the Bleak library to write a bytearray to a Bluetooth device characteristic. The bytearray I’m sending is

bytearray(b'3x01x00-x00x00x00x00x00x00x00x00x00x00x00x00x00x00x00x1f')

However, in Flutter, I’m using the flutter_blue_plus package, which expects a list of integers to write to a characteristic. For example,

await c.write([0x12, 0x34]) 

is used in Flutter to write. How can I convert the Python bytearray to a format suitable for the write method in Flutter?

Note: I’ve tried following in flutter, but in vain.

Wrote:

await c.write([3, 1, 0, 45, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 31]);

Response:

[0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

Wrote:

await c.write([51, 1, 0, 45, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 31],);

Responses:

[51, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 50]
[238, 1, 0, 8, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 231]
