I mean something like this:
nope i havent
Hi Brum
Sounds as though you are getting there. I made some small changes to your Sketch, in particular it is necessary to control the decimal places of floats.
Sketch2.txt (2.7 KB)
#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // RX, TX
void setup() {
Serial.begin(9600);
Serial.println("Enter AT commands:");
mySerial.begin(9600);
}
void loop()
{
if (mySerial.available())
Serial.write(mySerial.read());
if (Serial.available())
mySerial.write(Serial.read());
}
well that may help but i still dont know why it won't work with this
Actually this following solution worked for me!
Connect the BT module with UNO the following way!
Vcc -----> 5V
GND ----> GND
Rx ------> Rx
Tx ------> Tx
power up the Uno, once done, Press the small button in the BT module. Actually, Now the module has entered AT mode (Although the led blink rate will not change).
Now open up the serial Monitor and set the baudrate to 9600 and Both NL&CR ....
Type AT and Module should be replying OK!
Cheers!
i/ve found it on the arduino forum but it doesn't wanna work for me
also it isn't responding again to the command AT, i have an module without key but with en on the back but assume it's still the same thing
In that case, you are doing something wrong because it works normally and it is impossible not to work for you. Besides, skip this topic, you won't notice any difference when you use it. At 9600 it will be more stable.
the problem is more that a mate uses a baudrate of 38400 for his code that's why i wanna change it
but i'll try to figure it out since it isn't the topic
Hi Brum_A
please take care that, depending on the HC0x firmware, the way how the shield is interfacing the AT commands can be different.
Please take a look here below:
And the baudrate setting command is:
Good luck.
Hi Brum_A
Here below you can find a HC05 datasheet with interesting setting hints.
Hoping it can help.
Cheers.

And this is how to connect a 3.3 module to a NANO . Don't care about the Arduino board: the important thing is the resistor partition used to avoid to bake the shield's receiver pin.
All the best !
i got the dame divider just got RX and TX to pins 0 and 1
I'm still struggeling with the fact my app doesn't make a correct file i've listed what i'm trying to do and my block diagram below. I chanched some things because the format of saving wasn't the correct one but now i deleted the file and changed my block diagram to this and the program won't create a new one, it only asks permission to my files.
How I want to capture data.txt (422 Bytes)
but for some reason it doesn't create the file anymore, and even if i make the file beforehand it doesn't store to it
Can you send your .aia file?
