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.

@DanielEkeHead 6 лет назад

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.

Hello Greatscott! 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.

What if you want to use a Bluetooth board to be a single switch? My car is semi automatic with tiptronics. I guess the manual gears are changed with two wires. One being an up shift switch and the other down shift. I want to use a Bluetooth board to connect to paddle shifters to be the signal to hit the switches. Think these are good for that?

@rafal.zbojak 5 лет назад

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.

@radovanjuran8478 6 лет назад

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.

@andreasmuller1142 5 лет назад

thanks! No COM-port support is a huge downgrade. I wonder why it wasn't mentioned in the video.

@ams0063 6 лет назад

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.

@tuc151 6 лет назад

Great video, anyway Ebay is full of HM-10 clones, beware of that. I spent a month finding why my diy e-longboard is not working, HM-10 clone...fortunately I found solution how to firmware upgrade it to the "original" HM-10 via Arduino and some Windows commands :D. You can detect fake HM-10 by missing external oscilator on the PCB...

BLE has the option to send broadcast packets without pairing, it's used e.g. for beacons or sensors.

@Meikle641 4 года назад

Where's the best place to look into that?

@TheDryparn 4 года назад

You forgot range and robustness. BT4 has gained robustness functionality, similar to features found in Zigbee, so it will keep connection in harsher environments like thick walls, through floors and long distances.

@bergamt 6 лет назад

Another thing to keep in mind if you’re on iOS, the Core Bluetooth framework is BLE-only, and gives you a bunch of control over the connection from inside your app.

@martyncurrey3234 6 лет назад

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.

@hadrienberthet2575 6 лет назад

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

@firecasts 4 года назад

@ABaumstumpf 4 года назад

Funny how the chip used in the bluetooth-module already has a micro-controller included that gives the arduino a run for its money :P 8/16bit timers, 8K Ram, I2C, USART, 12bit ADC - quit a decent thing.

@Alacritous 6 лет назад

The funny thing is that these boards are all as programmable as the ESP8266 and ESP32's are. But the manufacturer hasn't been as community friendly as Espressif is. Which is kind of a shame.

@dege10000 6 лет назад

Yeah, you can flash the hc-05 a new firmware to give it HID capabilities.

@kfishy 6 лет назад

The CC254x chips use 8051 CPUs which are far more difficult to program; they have no GCC available for example and good luck finding a C++ implementation.

@Alacritous 6 лет назад

That's my point. the manufacturer hasn't provided a toolchain like Espressif did. The devices themselves are just as capable, but without the toolchain their use is limited.

@jp_engineer 6 лет назад

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.

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

@AlbertArmea 6 лет назад

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.

Hello Scott! Great! But you didn't considered the other side, that is the phone. Doesn't it also saves lots of power there also?

@jamesmaxwell381 6 лет назад

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

@SverigeKodar 6 лет назад

You are missing GATT. BLE has support for GATT services. They can be setup so that they notify the master when their data has changed. So you can use it for sensors, so that you only pull the sensor value if it has changed. Also, you don't need to pair. If you get the MAC, you can (on android at least) just tell the BLE service to connect that that MAC and it will do so if in range. Not sure about 2.0, but on 4.0 BLE you can get up to like 450 meters rage with an SMD antenna. Source: I work with product development and has used BLE (HM-10 for pre-study and better one for actual products) as a part of my job.
