$200-750 USD

Paid on delivery

We have a working ESP32 based device, developed using the Arduino core (with the Arduino IDE). We need to add the following network functionality: - We need to be able to configure the network with the "ESP Touch" or "ESP8266 smart config" mobile apps. The ssid/pass should be permanently stored, and automatically used on the next reboot. - The device should http post to a defined URL once every few seconds, posting the values of some 20 internal variables. The response from the server contains the same variables, which should be updated if the values differ. The binary format of the request will be provided. - We need a OTA update function that downloads a binary ESP image from a predefined URL, and burns it to flash. If the update is successful, it should reboot into the new image. We cannot provide physical access to the device, but all the schematics and documentation are available. The code is hosted on bitbucket/github, access to it will be provided.

I've did a project for a client in Euro which covered all your requirements. Pls check my profile for more information about that project. About this project: 1. SmartConfig & saving wifi credentials: ok 2. Posting and Parsing data: should NOT use binary format. You'd better use JSON and RestAPI. Pls do some google if you're not family with this. 3. OTA Update: Versioning must be implement to avoid OTA loop. A simple meta file on the web server can be used to store the version of the firmware. I don't need any physical access to your device nor your existing firmware. I'll use my ESP32 dev board for testing and use the latest ESP32 Arduino on github for coding => you can easily integrate the code to your device later and you'll do that integration yourself. About web server backend to accept the data - did you have it? Or do you want me to make a simple backend to accept the data from the ESP? I'll use NodeJS or PHP for that part. Cheers, Anh
