lillygo t-call esp32 logger changes

We build a datalogger from the following code.

[login to view URL]

with the following webinterface.

[login to view URL]

Now we need the following changes

1. Change current adafruit sensors to 2 ADC read (with 100 samplings) send a middled value to server 1 adc has temperature other has pressure on an analog sensor.

2. Change so that a digital out is on to activate a relay in order to activate the analog sensor described in 1.

3. Make unit able to save logs in memory and upload in bulk

e.g 24 logs over 86400 seconds.

4. On first startup every unit should upload a JSON file to the server, with IMEI number ([login to view URL]) this file should include as already mentioned:


Upload time

Log time

5. point 4 is ONLY on startup, each time a unit goes up after this, it has to check the [login to view URL] file on the server, and change values accordingly.

6. Do the changes to the http post, so it accepts bulk entries (keep in mind this also means you need to include RTC in the unit, since a date/ time for the readings are needed)

This is quite simple and there is a lot of examples out there.

The basics are made here and working fine.
