Bluetooth HC-06 Send/Receive image.jpg file to/from Arduino. SdCard Reader. Text file

3.- Change baud rate in HC-06. AT commands. HC-06 has 9600 bauds by default. Let's change it. We make this connection. Notice that I have now connected the module to terminals 2 and 3 of Arduino. [sdcard4c] We load this sketch: // Juan A. Villalpando // http://kio4.com/arduino/9L2_enviar_archivo_BT.htm #include <SoftwareSerial.h> SoftwareSerial BT(2,3); void setup() { BT.begin(9600); Serial.begin(9600); // BT.begin(115200); // Serial.begin(115200); } void loop(){ if(BT.availabl…

Bluetooth HC-06 Send/Receive image.jpg file to/from Arduino. SdCard Reader. Text file

6A.- Arduino with SdCard sends a file to the App. In the Arduino SdCard we have the following file: servo.txt 1,2,3,4,5,6,7,8 -1,-2,-3,-4,-5,-6,-7,-8 10,20,30,40,50,60,70,80 -10,-20,-30,-40,-50,-60,-70,-80 100,200,300,400,500,600,700,800 -100,-200,-300,-400,-500,-600,-700,-800 [sdcard4c] We send the character "k" from the App to the Arduino via Bluetooth. When Arduino receives the character "k", it sends via Bluetooth all the information contained in the servo.txt file of the SdCard to t…

Thank you <3 . I just got back home and started researching but can't still read multiple sensors from before I left.

I tried this but my problem is that, there is no label for what each data before the comma (,) is so I am still trying to do what to do.

@Jiii

there is no label for what each data before the comma

Labels are unnecessary - the data is always collected in the same sequence. Including labels complicates App reception via Bluetooth as each BT packet only carries a payload (your data) of 20 bytes - so best to keep the data size as small as possible and keep it practical, as per my example App Inventor file.

Sensors or Servo Motors?
