====== PIDflight Lap ======
===== How to setup Bluetooth module for lap timing device =====
By default most modules are set to **9600** baud rate. The Bluetooth module must be configured to **115200** baud rate. 

Please be aware the AT commands to configure your Bluetooth module may vary. Below are examples of typical AT commands for most common modules. 

===== HC-06 =====
  - Connect the HC-06 to PC with an FTDI adapter (ensure RX and TX are crossed over). 
  - Open a serial terminal to the COM port on baud rate 9600.
  - Type "**AT**" into the terminal, a "**OK**" response should be returned. Proceed to step 4.
  - Type "**AT+BAUD8**" into the terminal, a "**OK115200**" response should be returned. 
  - All done! 

The following AT commands are used to configure the name and passcode on the Bluetooth module.
  * **AT+NAME<new name>** (e.g AT+NAMEPIDflight to set module name to "PIDflight") 
  * **AT+PIN<XX... X>** (e.g AT+PIN0000 to set module pairing pin to "0000")

<WRAP center round info 80%>
Some generic HC-06 modules labelled **ZS-040** may use a variant of AT commands to configure the module. If the above commands do not work, please refer to the **ZS-040** section below.

==== ZS-040 ====
These AT commands have been verified with **AT+VERSION** command that returns **VERSION:3.0-20170609**.
  * **AT+UART=115200,0,0** (sets the baud rate to 115200)
  * **AT+NAME=<new name>** (e.g AT+NAME=PIDflight to set module name to "PIDflight")


==== Arduino ====
An alternative option to setting up the Bluetooth module without an FTDI adapter is the use the **bluetooth-passthru.hex** with an Arduino Nano. This HEX file creates a software serial connection to the Bluetooth module on D6/D7 pins and relays input from the serial terminal to the Bluetooth module.

  - Connect the HC-06 to Arduino Nano:
    - Arduino (5V) -> HC-06 (VCC)
    - Arduino (D6) -> HC-06 (TX)
    - Arduino (D7) -> HC-06 (RX)
    - Arduino (GND) -> HC-06 (GND)
  - Flash the {{:pidflight:bluetooth-passthru.zip|}} HEX file to the Arduino Nano.
  - Once the HEX file has been flashed, open up a serial terminal (e.g. Serial Monitor within Arduino IDE) to the COM port of the Arduino Nano with baud rate 115200.
  - Type "**AT**" into the serial terminal, "**AT> OK**" response should return to indicate the Bluetooth module is responding to AT commands.
  - Proceed with configuring the Bluetooth module with AT commands.

===== HM-10 =====
This module is **supported** as of PIDflight Lap **v1.0.0-alpha.5**.

**This module should be set to 9600 baud rate by factory default and require no further changes.**

If you need to configure your HM-10 module to use baud rate 9600, following these steps:
  - Connect the HM-10 to PC with an FTDI adapter (ensure RX and TX are crossed over). 
  - Open a serial terminal to the COM port on baud rate 9600.
  - Type "**AT**" into the terminal, a "**OK**" response should be returned. Proceed to step 4.
  - Type "**AT+BAUD0**" into the terminal, a "**OK+Set:1**" response should be returned. 
  - All done! 

^Parameter^Baud rate^
|0|9600|
|1|19200|
|2|38400|
|3|57600|
|4|115200|
|5|4800|
|6|2400|
|7|1200|
|8|230400|

**IMPORTANT**: Please be careful, if you set the baud rate to 1200, the module may no longer support the configurations of the AT command. You may need to short-circuit the PIO0 to ground to restore factory settings.

The following AT commands are used to configure the name and passcode on the Bluetooth module.
  * **AT+NAME<new name>** (e.g AT+NAMEPIDflight to set module name to "PIDflight") 
  * **AT+PASS<XX... X>** (e.g AT+PASS0000 to set module pairing pin to "0000")
  * **AT+RENEW** to restore factory settings, recommend to issue a **AT+RESET** afterwards to restart the device with factory settings.
  * **AT+ROLE0** to set the module as slave.
