HC05 and makerhub

[amerMo]

I seem to have an error while trying to upload data to Arduino using HC05. Is the problem caused by maker hub ?

Have you configured the UART parameters on the HC-05?

You need to hook these up to a serial terminal like TerraTerm and configure them using the "AT commands".

Also have you properly paired the HC-05 and has it installed the virtual com port in Windows?

Thanks for your reply,

I was able to connect it to the computer  and showed the com port, but there’s always an error when uploading.

I’m sorry, I’m not a professional, I’m a mechatronics student, so it’s my 1st month using Labview. I’m sure I’ve about heard the UART, but I have no idea how it works, and I really have no clue what the TerraTerm-like serial terminal is!!

As I said you probably need to connect directly to the HC-05 (NOT through bluetooth) and configure the UART on the HC-05.

The easiest way to do this is:

1. Connect the HC-05 to your Aduino's Tx and Rx pins.
2. Connect a jumper from the Arduino's Reset to Ground
3. Connect the Arduino's USB cable to your computer
4. Now you will be connected to the HC-05 through the Adrunio's USB to Serial converter. (The Atmel chip is held in reset now so it will not interfere)
5. Use the AT commands to configure the HC-05
