-Bluetooth to Serial Port Module Overview HC-05 module is an easy to use Bluetooth SPP (Serial Port Protocol) module, designed for
transparent wireless serial connection setup.
Serial port Bluetooth module is fully qualified Bluetooth V2.0+EDR (Enhanced Data Rate) 3Mbps
Modulation with complete 2.4GHz radio transceiver and baseband. It uses CSR Bluecore
04-External single chip Bluetooth system with CMOS technology and with AFH(Adaptive
Frequency Hopping Feature). It has the footprint as small as 12.7mmx27mm. Hope it will simplify
your overall design/development cycle. Specifications

Given a rising pulse in PIO0, device will be disconnected.
Status instruction port PIO1: low-disconnected, high-connected;
PIO10 and PIO11 can be connected to red and blue led separately. When master and slave
are paired, red and blue led blinks 1time/2s in interval, while disconnected only blue led
blinks 2times/s. …
