Flutter + BLE send large data

Job ID: 33466428

Budget: €8 – €30 EUR

I want to send large command data to printer device via BLE (Bluettoth low energy).
I can send small data as much as MTU size, the device works well.
I send large data as piece by piece, the printer does not work normal.

How can we do this?
