Thistutorial covers some of the common problems, and their solutions,when using Bluetooth Low Energy devices (BLE) or Bluetooth V4,Bluetooth V5 modules. However “Do you really need to use BLE?”
Ifyou just need some way to connect your Arduino project to your mobileor PC then a much better and easier solution is to use a BluetoothClassic (Bluetooth V2) shield, like IteadBluetooth Shield, OR a cheap WiFi shield like this project,Cheap/SimpleWifi Shield.
Enolsoft pdf converter 3 1 0 download free. Youshould only consider using a BLE module if you need one of its uniquefeatures, such as very low power consumption, or you want to stay onthe “bleeding edge” of technology. The RemoteControlled Light switch is an example of a project that needs torun of very low current <1.5mA so that is does not need anadditional power supply.
CustomBLE – No Programming required provides details on more thehalf a dozen different BLE modules.
Thereare a number of problems with using BLE for general purpose control.
- Older mobiles and computers do not support BLE
- The Bluetooth SIG standard does not define a general purpose UART connection.
- Programming BLE control Apps is difficult.
- Programming BLE devices is not straight forward
- Some BLE modules/software stacks deliver the same message twice is quick succession
- Some BLE modules/software stacks drop bytes when sending long messages.
Older mobiles and computers do notsupport BLE
Bluetooth used to be easy to use, every Android andiPhone and most computers supported Bluetooth V2. The BluetoothSerial Port Profile (SPP) was the standard way to get a general dataconnection via Bluetooth and all Arduino Bluetooth V2.0 shieldssupported it.
Note: not all Android mobilessupport BLE. You can check if your mobile supports BLE with the freeNordicnRF Master Control Panel (BLE) android app . If your mobile doesnot support BLE, then pfodApp will not display the +BLE button in theadd/edit connections screen.
The BLE mobile hardware is still being ironed out. Onthe Android side, BLE support was introduced in V4.2 but that versionand V4.3 was very buggy. V4.4 improved the BLE support and laterversion should be better.
The only solution is to update your mobile phone orcomputer to a later one that supports BLE. Note: BLE V5 specificationhas just been release so you may need to update again shortly to useis enhanced features, like Mesh support.
TheBluetooth SIG standard does not define a general purpose UARTconnection.
Thebiggest problem with trying to use BLE for general purpose control isthat the SIG specification does NOT define a standard UARTconnection. Bluetooth V5 specification does not fix this problem.Where as Bluetooth V2 (Bluetooth Classic) defined Bluetooth SerialPort Profile (SPP) which was universal and easy to code, BLE does notdefine a replacement.
Thishas resulted in each manufacture having to define their own 'uart'service and your mobile app needs to know the details in order to useit.
Onesolution is to use a general purpose app, like pfodApp,which recognizes half a dozen or more common 'uart' services fromvarious module manufactures. pfodApp has it own general purposemessaging system, pfod. The pfod messaging system is particularlysuited for BLE because almost all the messages are very short(<20bytes)
NordicSemiconductor has defined their own UART service, which pfodApprecognizes, and which a number of manufactures use. There are appsfrom Nordic Semiconductor to let to test its uart connection, NordicnRF Master Control Panel (BLE) and nRFToolbox for BLE However even for this 'standard' there is someconfusion about the TX versus RX characteristic. pfodApp handles bothalternatives.
ProgrammingBLE control Apps is difficult.
Programmingan Android or IOS app to make a BLE 'uart' connection is non-trivial.There are services and characteristics to be handled and messagingdelays to be allowed for as well as the 20byte message limit of BLEV4.
ThenRFToolbox for BLE provides a simple 'uart' connection if and onlyif the module you are connecting to uses Nordic's uart (correctly).The Android pfodApp onthe other hand provides a general purpose menu and graphical drivencontrol platform for a variety of different modules. The menus andgraphics displayed on pfodApp are completely controlled by the codein your Arduino or BLE module, no Android mobile coding is necessaryto get functional controls.
ProgrammingBLE devices is not straight forward.
Becauseof the lack of a BLE uart standard each module manufacture definestheir own, or does not define any at all. This means there is notstandard Arduino library for BLE. Some modules connect via Serial,some via SPI, some via direct library calls.
Thefree pfodDesignerapp provides a solution to this by letting you design pfodAppmenus and then generating the code for a variety of BLE modules. Evenif you don't want to pfodApp, the generated code provides you with atemplate 'uart' connection for you own use.
Some BLE modules/software stacksdeliver the same message twice is quick succession
Bluetooth Serial App
While testing a number of BLE modules it was foundthat some occasionally deliver the same message from the mobile app,twice in quick succession. That is within about 100mS. Depending ofhow your code and commands are structure this can be a problem.
Fate grand order ost download. For example if you use the same command to toggle aswitch on and off then you will find the switch stays OFF when youtry to turn it on because the second delivery of the same commandturns it off as soon as the real command has turned it on.
pfodAppV3.322+ overcomes this problem by adding a sequence number/letterto each command and and the pfodParserV3.17+ filters out any commands with duplicate sequencenumber/letter.
SomeBLE modules/software stacks drop bytes when sending long messages.
BLE V4 messages are limited to 20bytes per message.BLE V5 allows longer messages but it is very recent specification andmost of the software has not caught with it. Even if the module isadvertised as being V5 it probably still uses the 20byte limit.
Tosend long messages via BLE they need to be broken down into 20bytechunks and sent separately. You would hope/expect that module'ssupporting library would handle this for you. However in a number ofcases trying to send long messages requiring multiple chucks resultsin the end of the messages being dropped.
Bluetooth To Serial Module
ThepfodParserV3.15+ library provided as pfodBLEBufferedSerial class that youcan insert between your prints and the BLE serial output to acceptthe full message and release it 20 bytes at a time very 200mS or so.This gives the BLE communication time to pass the message on to themobile.
Conclusion
BLEoffers some unique advantages, very low power consumption, ifprogrammed correctly, and the promise of a local Mesh. However it isnot without is problems. If you only need to communicate between yourArduino project and your mobile or PC you are better off usingBluetooth Classic V2 or WiFi (IteadBluetooth Shield, OR Cheap/SimpleWifi Shield).
Ifyou really need to use BLE, or you want to stay on the “bleedingedge” of technology, then pfodAppremoves the need to code an Android app and the free pfodDesignergenerates all the code you need for a variety of BLE modules tocreate general purpose menus on your mobile. While the pfodParserlibrary and pfodBLEBufferedSerial over come double delivery ofcommands and loss of transmitted responses.
