This project has 3 part,
PCB Hardware,Firmware inside that and Enclosure.
Firmware should have these capability :
* scan for BLE tags
* gather their list
* do some calculation on gathered list
* send them by HTTP/Json to our server
* also send device info to two server every 30 seconds.
* easy to configure
* connect to wireless networks easily.
* Web Based network configuration page.
Hardware should have :
* Base on ESP32
* Have lithium battery charger inside
* should be able to detect input power source (onBattery or AC)
Free lancer should select proper ready enclosure in market for this device.
We need firmware source code and pcb design files and one working sample of device.
High quality project is so important for us.
Using espressif firmware is recommended compare with arduino.
