I need an experienced programmer in ESP32, bluetooth and RTOS for connecting 6-9 ESP32 devices to android and iphone simultaneously via bluetooth and Wi-fi. The devices should connect seamlessly just like headphone connect to our phone. Data to be sent and received after connection is established: 1. From phone to ESP32s: ON command (make a digital pin High to turn on a relay connected at the end of it) 2. From ESP devices: From ESP devices, once ON command is received, a timer will start. There is a OFF switch connected to one of the GPIOs which will turn off the timer and send timer value to the mobile. The application running on phone does not need to have high level GUI. a basic one will also do. Functionality is more important. I would prefer someone who can come down...

I need to develop stepper motor controller using ESP32. The motor is Nema 23. The device is used on window opener. Therefore, maybe the terminal switch is necessary to detect start and end point. If you have a PCB design and firmware development. please contact me.

I am working on a project which is similar to transferring files to a GoPro, with the following steps: 1. Download file from a web server to an iPhone 2. Wait and check for the file to be downloaded onto an iPhone 3. Switch WiFi networks to a local ESP32 4. Transfer the above file to the ESP32 I have the code from various sources, but I am not successful with downloading and uploading the files. The server download seems to work, as I can check if the file exists and I can delete and re-download the file. The problem is I don't know the location of the file, as I cannot check it on the iPhone and if I complete the file check it always states the file is not present. This is the same for the file upload, it reports the file is not present. I think the issues is when w...

We have a fully functional Program which calculates some times using location coordinates and timezone and shows the same on 7Segment Displays. The program currently works on ESP32 without any errors or bugs. For our existing ESP32 program we have used Arduino IDE, We are looking for someone who can port the same to ESP12F. all the work will happen via Anydesk on our computer, Review of our existing code will be possible only after we award the project.

Hello, I would like to build a new PCB combining 2 open-source projects: Makerfabs ESP 3.5" TFT and ESP TouchDown (3.5%27%27) Everything is open-source, schematics, board design and bill of materials.

Hello, I have tested this sketch with a Nano. All 4 temperature sensors work fine. The problem is the rpm and weight sensor. The sketch only works if you reduce the output to 500ms or more , I need 100ms or better. Basically I believe the Esp32 with much more speed may work. If you are interested, can edit the code to use Esp32 and also test 100% yourself with your own components, please bid. Also bid your actual price. Look in the file section. Thank you for reading.

I am needing a developer who has created Fitbit apps before. Basically the app on the watch needs: 1) Display a garage door (just a generic png image as a placeholder is fine) and every X minutes or so. 2) It calls out to my ESP32 via and reads back the JSON data. 3) Depending on the data that comes back the generic garage image should say "open" or "closed". 4) Pressing the garage image will either send a "close" or "open" command to my ESP32. I'm not that familiar with how the Fitbit watch apps do and don't do so some info above may need tweaked. *************************************************************************************************************************************** Please note that this is Fitbits own OS ...

...similar to BLE Scanner app (by Bluepixel Technologies) on Google Play / iOS. It must be written in the MIT app inventor or Blockly so it can easily be ported over from mobile app to Arduino, M5Stack etc. Preferably need to use the standard MIT BLE extension as it has all the functionality needed for this app. Project brief: I have three BLE devices called GMA1, GMA2, GMA3 - all using a HM-10 BLE 4.0 module. There could be more BLE devices in the future and all will have the GMA# naming convention. As soon as the app starts, it needs to scan specifically for these devices and ignore anything else in the vicinity. The app needs to read the RSSI (signal strength) and display this for each GMA device found. This would be similar functionality to the pr...
