What is the probability of error for serial Protocol via Bluetooth?

Com port over bluetooth.
what is the probability of transmission failure ?
The printer has no means of integrity monitoring.
The bytes just sent.
When you distort data . Amount of data instead of an image is printed waste.

Want to know how often this theoretically should not happen, provided that
next the other device can play music on Bluetooth speaker.

Must not distort, as the checksum is checked at the level of the L2CAP Protocol, which works RFCOMM
In practice printers sometimes fails.
there is a stream of bytes. there are 8 bytes beginning image. behind them a portion of the binary data. if one packet drops out, the part of the binary data is printed as text. I send portions is not a multiple of the package.
24 * 42 bytes plus headers from 5 to 8 bytes.
I think the channel is still not to blame ? Just next play Bluetooth speaker, when I sboynulo several times in a row. - Damian43 commented on April 7th 20 at 11:08
