I am trying to upload code (simple blink example) from Android (ver13) tablet to Arduino Nano using an HC-05 board and Bluino software. I know this should be easy (it says so on every tutorial I've read) but after reading hundreds of tutorials and viewing hundreds of YouTube videos I am afraid I'm still getting nowhere.
I can upload perfectly OK from PC so I've got a rough idea what I'm doing and obviously the nano board is OK. I have paired the HC-05 with the tablet (and managed to change it's name (via PC) to keep Bluino happy) so assume the link between Nano and HC-05 is working.
In Bluino I have changed the BOARD options to 'nano' and 'bluetooth'. When I press the 'compile' button it compiles fine then says 'uploading' then goes to 'error uploading' and does nothing else, no indication what the error is.
I've noticed it also does exactly the same whatever board is selected.
This has been driving me insane for weeks now so if anybody has any ideas what I'm doing wrong or got a link to a tutorial which actually works it would be greatly appreciated, thanks.
