    In this VS episode we will have a closer look at the most common Bluetooth boards for the Arduino. Along the way I will present you how easy it is to implement such a board in a Bluetooth project and whether it makes sense to use Bluetooth 4.0 (BLE) or whether we should stick to Bluetooth 2.0.

    Nicely done.
    Another really important difference is that the HC-05 BT2.0 boards DO NOT WORK with iPhones. That's because Apple refused to pay the licensing fees for this relatively old BT standard. So if you want your application to work with iPhones then you need to use a more modern BT standard like 4.0, eg the HM-10.
    So, if you care about iPhone compatibility use BT4.0LE via board like the HM-10.

    I’ve got the same cheap chinese version. You can find tutorials online how to flash a genuine HM-10 firmware on it and then you can use it as intended.
    Also, one more advantage of the Bluetooth 4.0 is the iBeacon mode, which can be used to track the distance from the device without even connecting to it, so it can last for years with just a coin cell battery.

    This demonstration is really awesome. You have made many cool projects about wireless control or connectivity using those Bluetooth devices. That makes them fun and smart. But I think if you can make a projects about radio connectivity or control instead of using those Wi-Fi or Bluetooth devices, that also be awesome.

    You forgot about one nifty thing that might convince some people to switch from HC-05. HC-10 can work as an iBeacon.
    What that basically means is that it can broadcast its data to more than one device at a time. Useful for something like sensors that don't need to receive data from controller and if they do need to receive something like a config change, you can easily switch them back to Central + Peripheral mode, receive data packet and go back to Broadcaster + Observer.

    Not sure if this has been pointed out below but the BLE module you have is not a HM-10. It might be worth adding, although these boards use BLE technologies the UART layer hides it from the user. They are designed as a simple serial cable replacement the same as the HC-05.

  • @TheDryparn

You can detect fake HM-10 by missing external oscilator on the PCB...

  • @jp_engineer
    @jp_engineer 5 ปีที่แล้ว +1

    Since I have checked HC-05 works great, but not suitable for small battery application...
    Hm-10 has a lot of models with a lots of firmwares,so the best you can do is to use the command "AT+HELP", gladdly it will shows up all the commands implemented....
    HC-05 to HM10 - Watch out not every Hm is pin to pin compatible.
    Hm10 - Once you power on, you're in AT commands mode, after pairing you automatically exit from AT command and gets into serial port mode.

    Thank you for the video! :) I'd like to contribute by sharing my own experience with Bluetooth LE and more advaced projects. I was supposed to make tiny coin-battery powered device, let's say some sort of a "smart sensor" - as it had PIC MCU, accelerometer and BTLE module. Bluetooth 2.0 uses good old serial COM port, so it is really simple to operate and use, especially when you can't use just pre-made terminals and have to create your own application to collect, process and save the recieved data. But Bluetooth 4.0 and higher are far more complex, although they still use UART in fact, it is not COM-port-based and that simple anymore.

  • @ams0063

    Some more features of this board -
    1. The HM-10 is rated to operate at a supply voltage of 2.0 to 3.7 volts, and its I/O are 3.3V tolerant.
    2. HM-10, 11 and 12 all use TI's BLE4.0 CC2540 chip.
    3.Requires up to 50mA
    4. Uses around 9mA when in an active state
    5. Use 50-200uA when asleep
    6. RF power: -23dbm, -6dbm, 0dbm, 6dbm
    7. Default baud rate for the serial connection is 9600
    8.The main modes of operation are called the advertising mode, scanning mode, master device, and slave device.

    Nice video. About the round-trip delay measurement, Did you use Android's methods to get the current time? I think the whole Android OS timing is not exact to ms level, and also there is the non-real-time-ness of both transmitter OS (Android) and receiver OS (windows?). Maybe a better time analysis could be achieved by attaching a logic analyzer to RX/TX pins of transmitter and receiver modules. This way you can circumvent the OSes

    I've done an entire project on BLE in engineering school. It seems easy to use, but it sometimes work terribly bad, apps do not always pair or allow you to do what you want.. More advanced arduino projets using bluetooth can be a pain in the ass!
    Other than that, we did a few tests with it, and BLE modules seem to have globally the same range as bluetooth 2.0, they consume waaaay less energy (as you said, good for long lasting applications), and seems to be more reliable in terms of pairing

    I don't know if this board supports it, but the real power of BLE is GATT, which allows you to broadcast and receive data without pairing. Supposedly GATT also uses less power, but I haven't been able to measure it because I've only ever used it between Android phones.

    While watching this video, i got an idea: maybe i can connect two phones to that system and find a way to send a message for one phone to another. I don't know if it's a good idea, but i think it's worth a try.
    I am not that good at software and hardware, but i would love to read your suggestions about this topic.
    P.S Maybe you should do a DIY or BUY episode on this.

    Is it possible to extend the range distance of the Bluetooth? How? If not, can you suggest a module that is a long range Bluetooth?

    all in all
    it is the way forwards
    4.0 headset lasts for many hours past a work shift ,it never runs flat like the 2.o ones used to do
    (for pro drivers on the roads who need headsets connected up all day then ,4.0 to 4.2 headsets are a must if you want to stay headphone connected up to your mobile and it last the full day DRIVING SHIFT )
    so if your headset is 2.0 and does not last you a full day -simply look for the 4.0 headsets and this is just the start of a great new world in Bluetooth technology
    i give it the thumbs up

    BLE board draws 120uA in sleep mode and can be powered by a coin battery. But, usually it needs to transfer data occasionally when it requires 9mA. So, do we need a seperate power configuration when transferring data. How to configure the power sources in that case?
