HC06 configuration

Projects Programming
1

Good morning

I am trying to configure a HC06 module, Slave only .

If I send the AT command via the Serial panel, I get answers as a chain of two numbers (68, 55, 13, 10 for instance, etc). I suppose they are ASCII values. IfI am right, how do I get to have them in alphanumeric instead ? I need to read the default standards before feeding them to the HC05 Master I have.

2nd question: is it possible to modify the default settings ? How ?

3rd question: on a UNO and/or Nano, do I have to cross RX and TX ? I have read both possibilities, how do I find out which case applies for my modules ?

Thanks a lot

If I send the AT command via the Serial panel, I get answers as a chain of two numbers (68, 55, 13, 10 for instance, etc).

Those two numbers being:

  1. 68
  2. 55
  3. 13
  4. 10
    ?

Looks like FOUR numbers to me.

68 is the ASCII code for D
55 is the ASCII code for 7
13 is the ASCII code for carriage return
10 is the ASCII code for line feed

IfI am right, how do I get to have them in alphanumeric instead ?

Use the correct type for the variable that the data is stored in (char, not int).

Yes, use the AT commands.

3rd question: on a UNO and/or Nano, do I have to cross RX and TX ? I have read both possibilities, how do I find out which case applies for my modules?

Yes they need to be crossed and you also need to make sure that the TX from Arduino is dropped to 3V if you HC06 has 3V signals. A voltage divider made from resistors is sufficient.

Online search for a datasheet for you module should have all the details you need.

Thanks a lot to everyone !
I now know better how to get further.

Have a good evening
