 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

hi , last night i have buildt my own app for Android devices which provide bluetooth serial support for Micromite and Maximite with the JY-MCU Vers.1.05. Wlan is also posible but the wifly modules are not really cheap . For Ios u need a jailbroken Device and only wlan is Suported. i think this is usefull for Robots /Cars etc. If anyone need something special, i can create him an App in Geoff 's Style . gtx |

Wow Plasma...! Do tell more... So, you have a android app you created that sends data to the phone's Bluetooth transceiver and send commands to the uMite..? (sweet)... Is the radio link work both ways..? Can uMite update objects on the phone..? If so, this is kick-ass..!!  I for one would like to know how to do this..! What kind of tool chain do you need on the android side..? What transceiver is used on the uMite side...? Anyway... Nuff... Sounds neat man..!!

I use this little bluetooth module, it works with any microcontroller who have serial peripheral. https://www.sparkfun.com/products/12576 
A PC with bluetooth will recognize it as a serial port and then is easy to communicate with the microcontroller. It covers a distance of 10 meters but there is a device who can cover 100 meters. I find it expensive if you intend to equip with it every "satellite" who is part of your home automation (and who is reporting back to your PC or mobile device), but as a single device for development is great. Anyway, I find Android development a little harder for me, as I am not a fan of Java. There is Qt 5 but not yet good enough.

Hello I use this Bluetooth module to connect to my XX-mites. Makes it easy to sit in my livingroom and program my devices in next room. Works like a wireless serial cable replace. I use App Inventor to make apps for Android, a free and easy tool to make small apps. Easy to handle Bluetooth, Wifi and communicate to XX-mites. // Jörgen |

I've done it via USB and they're about $1.50 (same as in laptops and tablets) -- but you need host USB and mites are short of that really. Maybe with the PIC32MZ. Same way provides WiFi and thus the net. I've used those BT modules but pre-soldered on a carrier that provides pins, just look on ebay. John |

hi , For Wlan with Ios and Android i prefere Glbasic .glbasic For Glb is no bluetooth availble ( will come but not yet). Glb supports a lot of Plattforms , so i prefere this. For Android only and Bluetooth i use B4a basic4android . With booth i can share content from or to the handy / Maximite. For Ios u can use only a Wlan module because the Apple restrictions. U need a jailbroken iphone / Ipad also . Booth Tools are not free , so i ask here if anyone need a Personal App. For his House or a Robot or something. Show me your Gui Design and the Commands to send . A Community Solution is also possible . A Backshed App for receive sensordata or something. Gtx |

Wow Plasma. I would love a simple app: Bluetooth to take in some serial data and display it. No outgoing control at all. Do the same as on the video with no send function. Price to do this??? Any interest? Muddy0409 Don't poo poo conspiracy theories. Remember that everything ever discovered started somewhere as a theory. |

ok muddy0409 , no problem . i do this : after connecting the bluetooth the app sends an "ok" to the micromite. the micromite get this "ok" as a startcommand to know the handy is allready on. now the pic sends the data . the android handy ask every 200 ms for incomming messages from the micromite. if so it shows the data . the gui have only one textfield for the incomming data. if you use an old slow Handy so show me the name from. 3 questions : how much data u send for one message ? how many millisecs between the messages? how long is your session for logging ? i need to know this because i need to prepare the receivebuffer . if you cant say this i build an universal app for you. "Geoff Style" from above mean " free" so no money to pay for. gtx |

Thanks for the reply. String would be 16 or 21 characters, ending with CR/LF Time between messages will vary. App needs to be listening at all times for something to come in. Session time could be any length. Data does not need to be logged to memory, only printed on screen. If the screen fills, the screen would scroll down to display the last 20 (depends on screen size) messages received. Anything that scrolls off the screen is lost. More info if you need more?

Hi Plasma, We have all been asleep in AUS (you posted 1:15 Melb time) and we are only now getting up with big hangovers from Saturday night partying... 
I am sure people will comment for you.. After the old `hair of the dog' (hangover recipe) kicks in. regards, Mick Mick's uMite Stuff can be found >>> HERE (Kindly hosted by Dontronics) <<< |

OK. Downloaded it and hopefully sent it to my phone. Now I just gotta find where it went and make it go. Stay tuned. You really gotta be a kid to work this stuff out, don't you? Don't poo poo conspiracy theories. Remember that everything ever discovered started somewhere as a theory. |

Rightio, found it (with a bit of help from the son), got it working. So far, looks pretty good, have not as yet communicated anything. That's next. Might take a day or two to seriously try it. Thanks a lot Plasma, I will definitely let you know how it goes. Don't poo poo conspiracy theories. Remember that everything ever discovered started somewhere as a theory. |

Hi Plasma, I still have not put this app through all its paces, but what I have seen is good. I still have to get my driving equipment built so I can do a full test. Will be a couple of weeks at least. Don't poo poo conspiracy theories. Remember that everything ever discovered started somewhere as a theory. |

Have purchased BlueTooth serial module to attach to my Duinomite Mega for wireless data input this one : >> http://www.dx.com/p/jy-mcu-arduino-bluetooth-wireless-serial -port-module-104299#.VDHoMvmSx8E Now i have got it working so far ( from both my PC over BT and Android phone BT)to the Duinomite ... 1. Pairs OK as HC-06 device attached to serial port on DuinoMite 1a. Attached the new BT com port as console under MMbasic. ( Open "COMx:9600 as console) 2. Data from Duinomite console appears(echoed) on remote console ( PC VT100)or on Android just fine .. ( connected at 9600bps default) 3. Key strokes are sent from PC VT100 terminal over the BT link but appear as garbage on the Duinomite MM Basic console. :( Any clues as to why its only working properly when TX from Duinomite but NOT OK when RX data at DUINOMIT MMBasic console ??? |
