Build, then understand.
Choose the problem you want to solve. Each article gives the prerequisites, a procedure, expected checks and the limitations of the setup.
To begin, start with the e-paper display without a network connection. The InfluxDB path then checks the data chain over Wi-Fi. LTE-M requires more preparation: an identified modem board, a suitable power supply and confirmed coverage.
ESP32 + SIM7080 + 1NCE
Identify your modem board, cross the UART signals, read AT responses and validate the cellular connection.
