Hello, I made HC-05 adapter, how was described by this link https://www.petoi.com/forum/hardware/add-bluetooth-module-for-uploading-sketches-and-communication?origin=auto_suggest, don't changed name and password, and plugged it. Next I downloaded application Code&Robots and connected via bluetooth. And when start selecting actions cat start beeping but doesn't any reactions. Can you help me please a bit, what I did wrong, maybe I need change a code or etc?
Does the cat work in normal condition with regular serial uploader?
yes
have somebody resolve this issue?
The Instructable post is missing a 10 uF capacitor between the DTR and reset pin. It's required for auto uploading the sketch. But the serial communication should always work.
In your video, the serial is receiving commands but not recognizing the character. Probably related to baud rate or frequency. Have you set up the HC-05 module with "at" commands, as described in the Instructable post?
Could you try the Arduino example codes ASCII Table to check whether the serial is working? It should print out a table in the serial monitor.
Thanks, work properly!!! I found some additional info about HC-05 http://www.buildlog.net/blog/2017/10/using-the-hc-05-bluetooth-module/ note: 1) to know the default variable add "?" Ex: AT+NAME? otherwise you will get ERROR[0] 2) lowercase "at" not worked for me 3) AT+VERSION was v4 4) AT+POLAR return ERROR (but without this setting it work normal. In this link you can get a bit info about this settings (http://www.buildlog.net/blog/2017/10/using-the-hc-05-bluetooth-module/) 5) after AT+ORGL it restarted and you need to reconnect and change HC-05 mode 6) to change MODE need plug on power, than press reset button and keep hold it, then plug on power, LED would blink 1 times to 2 second
Thanks for help!!!😎
