Are you sure there aren't two serial ports for this BT connection, one to
receive (read)- also called 'outgoing', and another to send (write) - also
called 'incomming'?

In this case, you'd need two separate instances of the serial port object,
one to send and the other to receive.

Note, I haven't used your printer, so I'm speculating (often BT devices
assign a single SPP port), and if this isn't the case, I don't have another
suggestion.

Hello,

normally you can send and receive over the same Bluetooth SPP
connection. This distinction sending or receiving SPP port (dev A/dev B)
is only relevant for the initiation of the communication. Later it's
unrelevant. I assume the communication is started by the CE device and
not the printer.

Greetings

Markus
