TM-P60 Technical Reference Guide 1.6 Bluetooth Protocol The protocol for printing to the TM-P60 via Bluetooth is shown below. Host Device (Master) TM-P60 (Slave) Printing data abcd Software provided by the customer Printing application Printing hardware software SPP connection Bluetooth connection tool Bluetooth host software Bluetooth module Software Hardware Bluetooth module Software Hardware The TM-P60 operates as the slave device when Bluetooth is used. Communication settings etc. are made on the master device. The master Bluetooth device comes loaded with a mechanism to connect via the Bluetooth protocol but is not loaded with a printing application.
The user must therefore develop an application for the master device for printing to the TM-P60. Epson does not provide a driver for the master Bluetooth device. Use the “ESP/POS Application Programming Guide” in order to develop a print application. 1.6.1 Security Bluetooth uses a frequency hopping (FH) method that changes frequency quickly and often when transmitting. This method makes transmitted data very difficult to intercept. Bluetooth uses radio waves that have a smaller range compared with wireless LAN, which limits the Bluetooth communication range. The limited range of the radio waves also makes data interception difficult.
Bluetooth also uses a passkey authentication system when communicating between new Bluetooth devices. An encryption function encrypts the communication data as well, making it very difficult for data to be decrypted by an external device. Rev. C General Information 1-7
