Hc 05 At Commands Not Working

I put the module in at mode by pressing the button on the module and removing power connecting power again and releasing the button.

Hc 05 at commands not working. 9600 bps data. This is a demo that hc 05 is a master device and communicates to hc 06. Follow these steps in the stated order to switch to the hc 05 to at command mode. Browse other questions tagged arduino uno bluetooth hc 05 hc 06 or ask your own question.

Hc 05 key arduino pin 9. Using baud rate 38400 send the at role 1 r n to module with ok r n means setting successes. At commands not working for hc 06 on arduino uno closed ask question. The led on my module is indicating all states correctly at mode paired discovery.

Alternatively for hc 05 you can use an arduino board. 8 bits stop bits. I paired both devices using my phone as master and the hc 05 as slave and when i am sending commands to the hc 05 through the arduino the pin key from the hc 05 is set to high 3 3v. Have you tried it with 9600 baud.

1 bit parity. When the hc 05 enters the at command mode it will communicate at 38400 baud rate. I am attempting to modify the configurations of my hc 05 bluetooth module by using the at command set. The problem is that i need to measure the rssi from my phone and using the command at inq the response from the hc 05 is ok and nothing else.

Hc 05 gnd arduino gnd. According this description this is the default rate if you not set the module into command mode at startup the default mode is data mode and this is the default configuration that may work fine for many applications. But as there are commands to change it it may not be in its factory condition right now. This video is to show how to configur.

The method by which i m trying to do this is by implementing the following connection. Hc 05 rx arduino pin 11. Before you connect the arduino to the usb remove the vcc power red wire from the hc 05 so it s not getting any power from the arduino. Wire the hc 05 and arduino uno per instructions.

Good evening like i said in the title i m not getting any response from my hc 05 module when in at mode. Power on module enter command state step 3. After sending the command at name blue the name of the device is not changed to blue but remains hc 05.
