    Need support with setting up 2 custom esp32 to record GPS data to my own test traccar server. I am using the below code / tutorial as my basis however if you have better code then we can use that the aim is to have the esp32 record GPS data every 2-3 seconds The 2 esp 32 are: LILYGO-TTGO-T-SIM7000G-ESP32 LILYGO® TTGO T-WATCH SIM868 version ESP32 WIFI/Bluetooth capacitive touch screen GPS GSM IOT for Need support with the code to ensure it works Details of uploading it onto the esp32 i use the standard Arduino software for this Validating and reviewing log files from Traccar to ensure it is receiving the data and troubleshooting if it is not Should have experience with Traccar and ESP32 and hopefully have even done this with your own esp32s so we can use the same code.

The name of the photo will be the time of its creation. 2) automatically start with Jetson Nano start and will automatically turn off after an external power cut (I'm using UPS, so we can see external power voltage and battery voltage). Jetson nano must start when external power appears. 3) Video from the camera must be shown on the display. The display must be divided to show video images from each camera.

Il software dovrà prevedere la lettura di card rfid e inviare i dati della card ad un server. I dati sono riferiti ad articoli da ordinare semplicemente avvicinando la card, ogni card corrisponde ad un articolo. Il software dovrà inoltre dare la possibilità di inserire la quantità ordinata dopo la lettura della card e vari messaggi di conferma o errore. Dal lato server i dati dovranno essere ordinati per cliente, articolo, quantità (dati presenti in ogni card) Lo spunto lo prendiamo da questo progetto pubblicato :
