== Hardware ==
=== Features ===
* Support BLE 5.0 and classic SPP BT 2.1 version
* Only suitable for data transmission situation
* Only slave mode
* Tranmission 10-15 meter
* Uart buffer 1K bytes, rate 115200

=== Power supply ===
* 2.2-3.4V, recommanded to use 3.3V
* Support coil cell battery, or 2x 1.5V AA battery
* Boot instant current 20mA, and then enter into broadcasting and wakeup alternate mode
* standby & connected-mode current 4mA
* Low-power boardcasting mode 20uA
* Boardcasting for 100ms, and enter into sleep mode 400ms, total cycle is 500ms

=== Mode ===
* AT commands works only when non-connect status
* Enter into data transmission mode when in connected mode

=== LED status ===
* Output 1 second high TTL when boot
* constant high when in connected mode
=== Pin Definion ===
* LED: output boot or connection status
* GND
* RXD (R): Serial UART RXD
* TXD (T): Serial UART TXD
* 3V3: Power supply 2.2-3.4V

== Commands ==
=== AT commands list ===
* AT+CT set baud rate
* AT+CZ Chip reset Chip soft reset
* AT+CW chip reset to factory settings
* AT+CL chip low power consumption setting

* AT+BS Set BLE connection password This function is not implemented
* AT+QT query the baud rate of the system
* AT+QL query the low power consumption status of the system

* AT+TS Query BLE Bluetooth connection password Reserved

* AT+BM set BLE Bluetooth name
* AT+BN set BLE MAC address
* AT+TM query BLE Bluetooth name
* AT+TN query BLE Bluetooth address

* AT+BD set SPP Bluetooth name
* AT+TD Query SPP Bluetooth name

=== AT commands examples ===
Set baud rate
* AT+CT01\r\n Baud rate 9600
* AT+CT02\r\n Baud rate 19200
* AT+CT03\r\n Baud rate 38400
* AT+CT04\r\n Baud rate 57600
* AT+CT05\r\n Baud rate 115200
* AT+CT06\r\n Baud rate 256000

Set BLE, phone and SPP name
* AT+BMBLE-1234\r\n set the Bluetooth name to "BLE-1234"
* AT+BN112233445566\r\n Set the address of BLE. The address displayed on the mobile phone is: 66 55 44 33 22 11
* AT+BDSPP-1234\r\n set the Bluetooth name to "SPP-1234"

query the names
* AT+TM\r\n returns TM+1234\r\n, the Bluetooth name is 1234
* AT+TN\r\n returns TN+12345678AABB\r\n BLE Bluetooth address: 0xBB, 0xAA, 0x78, 0x56, 0x34, 0x12
* AT+TD\r\n returns TD+SPP1234\r\n, the Bluetooth name is SPP1234

enter into low-power broadcasting mode
* AT+CL00\r\n does not enter low power consumption mode. It will be effective next time it is powered on. Pay attention to power on again after setting
* AT+CL01\r\n enter low power consumption mode. It will be effective next power-on. Pay attention to power on again after setting

enable or disable BLE SPP function

* AT+B401\r\n enable BLE function. Of course AT+B400\r\n is closed
* AT+B500\r\n Turn off the SPP function. Of course AT+B501\r\n is turned on
* AT+T4\r\n Query whether the BLE function is enabled. The chip will return T4+01 or T4+00
* AT+T5\r\n Query whether the SPP function is enabled. The chip will return T5+01 or T5+00

=== Low Power Mode ===
* AT+CL00\r\n = not enter into low power mode
* AT+CL01\r\n = enter into low power mode

== BLE Function ==
Currently supports BLE pure digital transmission, and the chip can realize transparent transmission. At present, both BLE and SPP can only be used as slaves. That is, the "SERVER" side.<br>

Please note that once the Bluetooth is connected, the chip automatically enters the transparent transmission mode. No longer recognize AT commands. Be sure to search in the app

* 1. The main UUID is "FFF0"
* 2. The UUID of feature 1 is "FFF1", and the feature is "WRITE" and "NOTIFY"
* 3. The UUID of feature 2 is "FFF2", and the feature is "READ" and "NOTIFY"
* 4. The UUID of feature 3 is "FFF3", and the feature is "WRITE"

== Quick Start Guide ==
* Setup baud rate 115200, simple print data to serial
* Voltage supply must use 3.3V or similar, otherwise it will burn
* Default module name KT6368 XXXXXX ...
* Data communication at 0xFFF0 -> 0xFFF1
