$25-50 USD / hour

Hi, I've got a device (based on atmega328) I'm looking to add some functionality to. Currently, it rotates a stepper clockwise/counterclockwise based on the buttons pressed, with double/triple/etc clicks moving it more. The first project: I have a programming port that I want to use to attach a bluetooth interface, and i'll communicate with it through my laptop. bluetooth interface is an HC-05 https://www.amazon.com/DSD-TECH-HC-05-Pass-through-Communication/dp/B01G9KSAF6/ref=sr_1_3?crid=2BQSHHXARNQH4&keywords=hc05+bluetooth+module&qid=1575218836&sprefix=hc05+b%2Caps%2C132&sr=8-3 commands to add are: U500<cr> - rotate clockwise 500 steps D1000<cr> - rotate counterclockwise 1000 steps V<cr> - return analog value of ADC7 (going to use to monitor battery voltage) ..the numbers for U/D will vary.. will provide circuit diagram and existing code

The HC-05 uses the serial port profile (SPP) - which belongs to the Bluetooth Classic (BT) specification rather than the Bluetooth Low Energy (BLE) specification. I develop on a Linux PC with a USB bluetooth dongle to communicate with the HC-05. Linux uses the Bluez bluetooth API. If you use a Windows or OS X laptop you would need to use a different library. For this reason, I suggest that - for the initial development - we use an Android mobile app to communicate with the HC-05 module. Do you have an Android phone to test with? If so ... There are several apps available in the Play store which allow the use of pre-defined 'macros' for sending commands to a paired bluetooth device - using the SPP (Serial Port Profile). Once we have verified that the command-set is suitable - and communication between phone and Arduino is working - we could look at communication with a laptop (if still needed). Regarding hardware ... What stepper driver do you use? I would probably use an Arduino Nano - as it is easy to use with a breadboard. If needed ... I can create a private Git repository to facilitate sharing and versioning of software. Due to other work commitments I would only be able to spend a few hours a week on this. I am based in Ireland. Please note the timezone difference.

Hi, I'm really interested in your project and I have the know-how (I teach Arduino/programming classes) but we need to sync our hardware. If you choose me then I need first to order your BT modules (so 2 days delay probably). What do you think? Regards Sorin

Hello! I'm an electrical and software engineer with a background in Robotics. I have lots of experience with Atmel AVR microcontrollers, as well as various actuators, sensors and communication protocols. I'm familiar with the bluetooth module you linked and it is very straightforward for me to implement the connection by reading from the serial passthrough. I'm comfortable working with either Atmel Studio or the Arduino software, whichever you are using. I'm able to get started right away and can complete this project very quickly so please, feel free to get in contact via chat!

Sounds simple enough! Here's my plan: * The atmega side of the code can be in arduino as well as c, as both can interoperate and your existing code isn't necessarily needed. * The BLE module I would prefer to code directly without the arduino middleware. * A nice command line interface on the PC that interacts with the bluetooth libraries/drivers Please feel free to message and discuss.
