Learning HC-05 but cannot get past basics

Even though I understand the serial monitor is working perfectly, you might just try having it run simultaneously with Bluetooth, Thereby checking that the problem really is exclusivel to Bluetooth.

In fact the data I show is close to simultaneously - the serial monitor shows my home time zone, the terminal program is in my current time zone.

@Nick_Pyner

You might configure Bluetooth and monitor to run at 115200, as this might be one of those times when speed really counts.

I’ll try that.

I set up an HC05 on my Uno and connected to serial Bluetooth terminal on my Android tablet. Running your code, I do not see the extra digit.

My luck! Thanks for doing that.

I suspect that the resistor network is on solderless breadboard and that the stray capactance and environmental noise is a potential concern

No, I created a purpose made jumper that includes the soldered resistors and connector for the HC-05.
