Preparing a 757-801

Configuration of the Bluetooth
The process for configuring the Bluetooth
is described in the manual for the Bluetooth
1. Reset the Bluetooth
2. Enter the MAC ID of your 750-644 I/O module in the list of allowed
devices (AT BTSEC ADEV ADD = <MAC ID of the 750-644 I/O
module>).
3. Enter the MAC ID of your 750-644 I/O module in the list of trusted devices
(AT CON TAR ADR = <MAC ID 750-644 I/O module>).
4. Enforce secure authentication (AT BTSEC AUTH = 1).
5. Exit configuration mode (AT LOGOUT) to start data transmission.
9.2.2

Preparing a 750-644

1. Reset the 750-644 I/O module to its factory settings.
2. Enter the Bluetooth
750-644 I/O module.
3. Bind the Bluetooth
ad-hoc devices and activating the respective slot ("Bind").
4. Put the 750-644 I/O module in "Ad-hoc Communication" mode.
9.2.3

Exchanging Data

1. Use a terminal program (e.g. HyperTerminal, HTerm or Realterm) to send a
character string from the Bluetooth
module, e.g. the character "a".
2. Go to the output data of the process image of the 750-644 I/O module and
set bit 2 to the value "0x04".
The value "0x16" must be visible in the process image of the inputs on the
first place of the slot (byte 2). Signaling "0x02 – RR – Receive request",
"0x04 – CS – Connection established" and "0x10 – LEN=1 – 1 byte data
received" are encoded in this value. The following byte should now contain
the ordinal numbers of the transmitted string ("0x61").
