The battery-powered mobile device is built on the ESP32 architecture. The device wakes up every hour (deep sleep), receives data from the sensors, sends it via the GSM channel via the SIM800 module via the MQTT protocol to the server and goes back to sleep. There is a sample code. All sensors are connected via the i2c or 1-wire bus: ADC1115 (2 pcs.), BME280 (2 pcs.), DS18B20. Basic requirements for the sketch: 1) Interaction of ESP32 and SIM800: GPRS connection, positioning by base stations. 2) Collecting data from sensors (about 10 pieces) and parsing them into JSON format. 3) Verification of sending data to the server and re-sending in case of communication failure (QoS). 4) Separation of sensors into two i2c buses. 5) Firmware update via OTA (MQTT). Phased delivery of work is possible. There is a sample of a working sketch, but without some features.

Hello, thank you for your job posting. I read your description about--Arduino I am a senior electrical engineer. I have plenty of experience in firmware development and micro-controller developments. I can write the firmware based on Arduino, Raspberry Pi, Pic, Atmega, FPGA, ARM, DSP, PLC and so on. And I can design the circuit by the Altium, Eagle, KiCAD, Allegro & OrCAD, PADs. I provide the services - Gerber files, Netlist generation, BOM generation and 3D Models of PCAD and ECAD. I am also good at AutoCAD, Solidworks. And I can simulate all circuits with Proteus, LT-spice, Matlab, Simulink, Multisim, and Labview as well. Due to my experience in firmware development, I will bring you the perfect result in time with high quality. I will also give you a detailed explanation of the process. Looking forward to hearing from you soon Thanks

This bid is for tasks 1-5 only (i.e. everything except the OTA protocol implementation). But firstly ... When do you need this work completed? Just to be 100% clear ... The SIM800 is connected to the ESP32 via UART, correct? And all internet communication is to be done using GSM rather than WiFi, correct? I think I would need to order some components (e.g., the ADC1115 and BME280) in order to replicate your hardware setup. These could take a week or so to arrive. When you refer to "positioning by base stations", are you thinking here of the AT+CIPGSMLOC command? I have some more questions, but I would need to know if the approximate budget is acceptable first.
