== Quick Start and Notice ==
About AT Commands
* AT commands at default rate 115200
* Commands no need \r\n
* AT+PASS123456 to set password to 123456, AT+MAC to check mac address: +MAC:A81B6A85C841
* Module in AT Commands mode when NOT connected. And enter into data transmission mode when it paired.
About Pairing
* No need to pair, set working mode and use directly
* master module can only allow one slave module connect.
About Sleep Mode
* Pull P00 to low to wake up the module from sleep mode, then module can accept data tranmission. This pin is internal pull up.
About hardware design.
* Power supply must use 3.3 or 3V for final products
About Features
* in room distance is 15-30 meters, max to 60 meters.
* Tranmission data speed is 1KB/s
* Do not support 2.0 or 3.0 bluetooth version.
== Features Modes ==
# Slave transmission data mode, APP tranmission mode
# Wechat tranmission mode
# iBeacon mode ( wechat shake or iBeacon mode )
# Sensor mode
# Master sensor mode
# Master observation mode
# PWM, RTC or IO control (command from host MCU or BLE data )
# iBeacon indoor location mode RTC
# Support LED product, vibration product mode

== Characters ==
* Tested on 3V3
* write data to support hundreds of bytes to write (for example, 512 bytes)
* Transmission distance 15 - 30 meters

|}

== Sleep Mode and Power Saving ==
* Command AT+SLEEP to put into sleep mode
* User can pull Pin00 down to wake up.
* default 100ms boadcasting current comspution is 500uA, 300ms is less than 100uA, in sleep mode no need boarcasting is 1uA
* Wake up BLE, then wake up MCU via BLE, will save power better

== Breakout Board NBL1061 ==
* PWRC - P00 wake up pin
* STAT - P16 bluetooth status
* LED - P05 Bluetooth boardcasting LED

For sleep mode
* P00 is wake-up pin, pull down to wake up after use send at+sleep
* P05 - broadcasting pin, blink when broadcasting
* P16 - Connection Status, TTL can be reversed
* P01 - normally low, when connected can still pull to low to enter into AT commands mode
