MBT

 MBT tool source code and download FW scripts for support platform

Version

  1.32.0

Requirements

• Programming language: C
• Build code Environment:

   OS: Ubuntu 20.04
  

• Build Tool, Use the following command to install the cross compiler:

  sudo apt install gcc-aarch64-linux-gnu build-essential
  

How to Build

 cd mbt/

for x86

 make clean
 make x86

for arm64

 make clean
 make arm64

##Binary execute file in Release folder and scripts folder

Folder Structure

<SCRIPT_FOLDER> for different Bluetooth chip script
- cyw5557x
- cyw5551x
```
-<SCRIPT_FOLDER>/
	- scripts_for_imx8/
	- scripts_for_nano/
	- scripts_for_xaiver/
	- scripts_for_rpicm4/
-Release/
	- arm64/
	- x86/

# HOW TO USE SCRIPT FOR DOWNLOAD FW

after build complete
copy <SCRIPT_FOLDER> to target board through usb disk or wifi or ethernet
cd <SCRIPT_FOLDER>
cd scripts_for_<BOARD>
<BOARD> is the target board you use. the script support 4 target board:
      RPICM4
      IMX8
      NANO
      XAVIER

DOWNLOAD WITH PARAMETER:
	sudo ./bt_load.sh autobaud
	sudo ./bt_load.sh auto3m
	sudo ./bt_load.sh softo3m
	sudo ./bt_load.sh minidriver
	sudo ./bt_load.sh normal
	Reset the chip to autobaud state and press ENTER key!
	REG ON
	.........
	.........
	Current state: Completed successfully

# TEST IN RPI4CM BOARD
## FOLOW THE BELOW STEP
## MBT COMMAND detail in readme.txt
## 1. scripts for autobaud download
   After build mbt and copy <SCRIPT_FOLDER> to rpicm4 board

cd <SCRIPT_FOLDER>
cd scripts_for_rpicm4

sudo ./bt_load_autobaud.sh fcbga_iPA_dLNA_ANT0

## 2. USE MBT OTHER COMMAND
set environment first

export MBT_TRANSPORT=/dev/ttyAMA0

## 3. reset

./mbt reset tx: 01 03 0c 00 rx: (7 bytes) 04 0e 04 01 03 0c 00

## 4. write_bdaddr

./mbt write_bdaddr beefbeef0011 tx: 01 01 fc 06 11 00 ef be ef be rx: (7 bytes) 04 0e 04 01 01 fc 00

## 5. read_bdaddr

./mbt read_bdaddr tx: 01 09 10 00 rx: (13 bytes) 04 0e 0a 01 09 10 00 11 00 ef be ef be

## 6. Tx AND Rx Test
PREPARE 2 RPI4CM board both have same copy of <SCRIPT_FOLDER>.
one run as TX,  another run as RX
### TX

./mbt tx_test beefbeef0011 2402 3 1 3 1 1 0 ./mbt reset to stop tx

### RX

./mbt rx_test beefbeef0011 2402 3 1 3 0

# HOW TO PUT or REPLACE FW
change your FW file name into FW.hcd

put the hcd file into scripts_for_<board>

# FOR REFERENCE
## YOU CAN MODIFY include.sh at scripts_for_xxx

BT_FW=FW.hcd

to what the name you want and change the FW with your name.
