Arduino Due and Open log to ESP32

Q&A Forum › Category: ESP32 › Arduino Due and Open log to ESP32

Hi
Do you have examples explaining how to read data saved in the Open Log SD card module and send it to ESP32 via TX and RX pins which I could read using the Bluetooth module on my phone?

Hi.

Unfortunately, we don’t have any tutorial using Open Log.

You can take a look at this tutorial by Sparkfun, it’s a very god one: https://learn.sparkfun.com/tutorials/openlog-hookup-guide/all

To send data via Serial from the Arduino to the ESP32, you just need to use the Serial library as shown here: https://www.arduino.cc/reference/en/language/functions/communication/serial/write?from=Reference.SerialWrite

You can also use the serial library to receive data on the ESP32 side like in this example: https://www.arduino.cc/reference/en/language/functions/communication/serial/read

I hope this helps.
