Re: Modbus Master Serial RTU without RS485
Use something like Baseblock ComTest Pro to sample the messages on a PC http://www.baseblock.com/
You will need to connect with FTD module od similar

Re: Large File Transfer via Bluetooth Classic to ESP32
Most of my BT classic is limited to low numbers of bytes so I thought that I would try larger transfers. This is the result of Bytes sent from an APP to an ESP32 using classic bluetooth, no delays introduced The bytes are send via an array which I populated with the same character. At the end of the...

Re: Frequency Measurement on digital input
II was really trying to understand what part of the interrupt caused the count delay but I didn't get to the high frequency input limitation. Except for the port call there is not much difference between your and my code... As to your frequency meter I don't have an LCD and was going to adjust your ...

Re: Frequency Measurement on digital input
Thanks for that
I tried your code against my original and didn't really see any difference in accuracy or stability. Can you explain what you saw with your code please.

Re: Bluetooth serial bridge
I cant see why it doesnt work
Have you tested BT recieve by using something like this
if (Serial.available() > 0) {
// read the incoming byte:
incomingByte = Serial.read();
// say what you got:
Serial.print("I received: ");
Serial.println(incomingByte, DEC);
}
}
