Re: Digital Input
I should have read your code better
You have to attach the interrupt to Pin 14 in the setup, not call it in the Interrupt routine
See
attachInterrupt( , ,)

Re: Digital Input
Have you tried something simple like a print statement in the interrupt routine to see if it's working?
Serial.println(micros());
Serial.println(micros());

Re: Esp32 update attached arduino?
You can program an arduino through the serial port so you should be able to make the ESP32 act as a data pipe, however you've got to get the new compiled program out of the IDE into the BT or WIFI connection to the ESP.

Re: ESP32 stops working for no apparent reason in field
Looks like a continuous reset. Perhaps a pull up resistor on the Reset line.

Bluetooth OutPut Power Modulation
I am seeing bad data on an Android Tablet receiving Bluetooth data from an ESp32 that has an external aerial. If I move the tablet away from the ESP then I get a better, but still not great, good data transfer. Is it possible that the BT output send signal is 'swamping' the receiver in the tablet? I...

Probably the reason that no one has answered you is that there are hundreds of answers to this on a simple Google search

Re: ESP32 Configuration File
You may be able to do this through storage to the onboard EEPROM.. Search programs to asses this

Re: ESP32 I2C read issue
The sensor, if it is I2C compatible should have a singular or range of addresses that can be used to read and write to it. If you cannot find this in a manual then search for 'I2C Scanner" this program will register all of the I2C nodes connected. http://www.ti.com/lit/ds/symlink/adc121c021.pdf Inte...

Re: Send data from one ESP32 to another
If you search this site you will find that using WIFI with Bluetooth is almost impossible due to the large compiled size of the two together. I have overcome this only by using two ESp32'a one for the WIFI connection and one for the bluetooth with a standard hardwired serial in-between There seems ...
