Hi Zerynth Team
I’m trying to send the JSON data from ESP32 to Raspberry Pi4 using the Serial Port2(IO16, IO17).
I’d like to know three things.
- Is it possible to send JSON data directly from the ESP32 to the RPI4 using the serial port?
- Is it necessary to use write() method to send the data? Or can I use only print() to send the data?
- The JSON data I want to send includes many bytes. From that point of view, is it reasonable to use serial port? Can it work reliably?
