3.6.5. BT Function
MC60 series module supports Bluetooth function. Bluetooth is a wireless technology that allows devices
to communicate, or transmit data/voice, wirelessly over a short distance. It is described as a short-range
communication technology intended to replace the cables connecting portable and/or fixed devices while
maintaining a high level of security. Bluetooth is standardized as IEEE802.15 and operates in the 2.4GHz
range using RF technology. Its data rate is up to 3Mbps.
MC60 module is fully compliant with Bluetooth specification 3.0, and supports profiles including SPP and
HFP-AG. For more details, please refer to document [14].
MC60E module adopts dual-mode chip, and supports BT3.0&BT4.0 specifications. BT4.0 supports
Bluetooth low power (BLE) technology, which is low cost, short-range and interoperable wireless
technology, and uses intelligent means to minimize power consumption, thus extends the applicability of
the technology to a wide range of extended applications, such as watch, anti-theft key ring, sports and
fitness sensor, health care sensor and remote control.
3.7. Power on and down Scenarios in All-in-one Solution
In All-in-one solution, GNSS function is turned on or off by the AT command sent from GSM part.
3.7.1. Power on
The module can be turned on by driving the pin PWRKEY to a low level voltage. An open collector driver
circuit is suggested to control the PWRKEY. A simple reference circuit is illustrated as below.
