There are some notes on using Windows in the childs' guide notes you have. Indeed I used windows before I got a smartphone.There are two entirely separate areas of operation.
- Data transfer between PC and Arduino
- Uploading and debugging programmes via bluetooth
The following addresses the first.
Bluetooth remains a slave
No changes at Arduino end - you have done all that
You need a Kosher terminal programme for the PC. I use RealTerm. There are others - all free. Using RealTerm is pretty intuitive and, once things are debugged, is a better way to go than serial monitor, even without bluetooth
PCs rarely have bluetooth out of the box. Any problems are likely to do with the installation of the bluetooth dongle. Device Manager will show you which COM port it is on. Things are easier with laptops with built-in bluetooth.
Uploading and debugging via bluetooth has been covered here recently. I know nothing about it.
My PC is a laptop. I will keep the HC-05 set to be slave.
OK, using RealTerm I am able to connect to the HC-05, on COM8 (Outgoing) I get a constant stream of info, pressing one of the capacitive sensors makes it slow right down, the HC-05 LED blinks twice.
Connecting to COM7 (Incoming) works but the LED still blinks on/off fast like it isn't connected.
I really don't know what I am doing with RealTerm.
Do I need to upload the sketch over bluetooth (COM7) in order for the sensors to communicate the script to the PC over bluetooth?
I have been reading on uploading over Bluetooth, the problem seems to be the Arduino doesn't know the right moment to reset, I'm not sure how this can be done easily.
