Bluetooth Modules Martyn Currey. Updated 2. 1. 0. There are many very similar Bluetooth modules available and sometimes it can be difficult finding out, not only which one you have, but also how yo use them.

AT 0. 9 Bluetooth V4. CC2. 54. 1Getting Started. Determining what modules you have and what firmware they are running is key to getting them to work and there are various things you can use to find more information. Markings on the board or the breakout board. Number and type of pins on the breakout board. The type of Bluetooth. The chips used. Talking to the module. But the first thing you should do is try it. Power it up, make sure it works and see what name it transmits. If it transmits HC 0. HC 0. 5 you know it will be Bluetooth 2. HMSoft, AT 0. 9, BT0. Fighting Sound Effects. CC2. 54. 0, CC2. 54. BLE. I am an Android user sorry I cant help with IOS so all the examples will be from Android devices. On Android devices that have Bluetooth, all Bluetooth 2. Settings Bluetooth Scan for devices. BLE modules may or may not show up depending on the Android device you have and the version of Android it is running. For BLE you should use one of the many BLE apps. I generally use BLE Scanner or B BLE but there are many others. Markings on the board breakout board. There are many different modules available and a few have become fairly popular. These general have a brand or some kind of marking on the board either on the small SMD Bluetooth board or the breakout board. Commons ones are zs 0. FC 1. 14. JY MCUCZ HC 0x. SJKeyes Bluetooth 4. HM 1. 0Of course, some of these are pretty obvious. If your module has HM 1. HM 1. 0. It gets tricky when there are no markings or when the same board gets used again. I now have several different modules BT 2 and BT 4 that all use the zs 0. FCC 1. 14 boards have at least 2 different firmwares. Number and type of pins on the breakout board. The number and type of pins can give you some information. For Bluetooth 2 modules HC 0. HC 0. 6s tend to have 4 pins. The pin labels can also help. Besides the common TX,RX, GND and vcc, there may be EN, WAKEUP, STATE, BRK, KEY, or LED pins Type of Bluetooth and chip used. This should be obvious but you never know. The chances are, if you bought a BLE module then you will get a BLE module just maybe not the HM 1. If you are not sure, start it up and use a Android device to scan and see what appears. The chip used on the small Bluetooth board the daughter board can help. Google the chip name and you will soon have a datasheet. Talking to the module. To configure any of the modules you need to talk to it using a serial UART connection see below for more on this. This can also be frustrating because different modules have different requirements for the format of the AT command. Some require uppercase, some lowercase. Some like line ending characters, other do not. Most default to 9. When trying new modules I have kind of settled on the following routine. I start with 9. 60. If no joy, I try lower case. If no joy, I remove the line endings and try uppercase again. After going through the various options at 9. I try 3. 84. 00. 9. If I still dont get anywhere I will try the other baud rates. I will also cycle the power while connected with a serial connection. Some modules, like the ones that use a Bolutek firmware, have a start up message. Getting garbage characters is a sign that you have the wrong baud rate. Connecting To A Computer. Please note that I am a Windows user so all examples use a Windows system. There are a couple of ways you can connect the serial Bluetooth modules to a computer either via a serial UART to usb adapter, or with an Arduino serial in serial out sketch or any other similar microprocessor. I tend to use an Arduino. I have a few slightly different sketches but I start with a very basic one. This takes wha ever you enter in the serial monitor and sends it to the connected module. Anything it receives from the module it displays in the serial monitor main window. Basic Serial Communication Sketch. Hardware serial is used to talk to the host computerArduino serial monitor and Alt. Soft. Serial is used to talk to the Bluetooth module. The sketch can be used to talk to any module that uses serial communication. The sketch can be used to talk to any module that uses serial communication. Basic serial communication sketch using Alt. Soft. Serial ASS. Uses hardware serial to talk to the host computer and ASS for communication with the Bluetooth module When a command is entered in the serial monitor on the computer the Arduino will relay it to the Bluetooth module and display the result in the serial monitor.

Check that the resistors are in the correct order the 1. K ohm resistor connects to the Arduino. Different baud rates. Not all modules use 9. Change the line endings rn. Some modules need them, other dont. Try upper and lower case. Check your connections. Android Apps. B BLEBLE4. Scan can be downloaded from Google Play. BLE Scanner is also available. HM BLE Terminal is available here. Please note I have some minor issues with AT commands appearing by themselves. Not sure if it is the app or me. Bluetooth spp tools pro is another serial terminal app that I have not tried yet but looks quite good. Bluetooth 2. 02. EDR Modules. HC 0. ZG B2. 30. 90. W Bluetooth 2. EDR modules. HC 0.
