What is the transmitting rate through a Bluetooth connection?
According to the Bluetooth Specification, the over-the-air transmission rate is 1 Mbps. This is the raw data rate; the actual data rate will be somewhat less depending on a variety of factors (basically how much traffic is present on the Bluetooth piconet). Note: The internal Bluetooth module in the printer has a UART interface to the printer processor set at 57600 baud. This rate is totally independent from the over-the-air transmission rate.
