Unit

• Switching ON/OFF procedures :

Switching on:

- The signal “NRESET” on the host interface is forced to a logical zero value by host until the supply voltage

reached its nominal value.

During this phase no component on the module is supplied.

- The host switch its signal “NRESET” to a logical one value allowing the module to turn on its supply.

- After 280ms, the supply gets stabilized and then triggers the start of the ASIC

- 100ms is necessary for the ASIC to start and give execution to the embedded software that will turn the module

into a permanent “active mode”

Switch off through software:

- The host sends the "sleep” AT command

- The ASIC disconnects any BT link

- The ASIC sends the "sleep acknowledge" AT command allowing the host to switch the reset to a zero logical

value.

- If the host activate the “NRESET” to zero for at least 5 us but no more than 4ms the module will be reset.

• VCC:

Supply voltage 3.3V(-0.1V/+0.3V) including tolerances, thermal changes, noise over/under shoot due to load change and/or car battery voltage change, load dump. Peak current: 400 mA during switch on (2 ms).

• 1.2V OPTIONAL POWER SUPPLY:

This optional allows lower electrical power consumption of CK5050. Operating Conditions: Supply Voltage for Logic Core: 1.2V (-0.04V/+0.12V)

4.4 Software Interface

The main target of the software interface is to provide a high level command set, hiding the internal complexity of the Bluetooth function and the variability of its standard across different devices.

This software interface is based on well-known AT commands. Some of these commands are directly derived from the GSM 07.07 recommendation and from the appropriate Bluetooth profiles.

Some supplementary commands are used to manage Bluetooth related functions like device pairing and connection management as well as the acoustic and speech recognition functions.

AT Command List and Bluetooth AT Command Software Specification is available.

BLUES supports Unicode, which allows the management of accents and phonebook in any language.

BLUES is also very friendly with a flexible MMI. One can use BLUES with a simple single or double key interface as well as a diversity of graphic displays.
