Im trying to connect to the Bluno Nano V1.3, what is the UUID I need to use in android studio?
By Leff
I don't know much about the UUID... but it can not be modified.

From the source code of our Bluno Basic demo, ..., I found the UUID applied to all our BLE products, that is

Code: Select all
public static final String SerialPortUUID="0000dfb1-0000-1000-8000-00805f9b34fb";
public static final String CommandUUID="0000dfb2-0000-1000-8000-00805f9b34fb";
public static final String ModelNumberStringUUID="00002a24-0000-1000-8000-00805f9b34fb";

What's more, as to how to know the iBeacon UUID, download a BLE finder from the APP market will help. As I installed the BLE UUID Explorer and find my bluno as:

Is it possible to do all that (discovery, connection, pairing, data sending) from an Arduino sketch?

What commands would I need to send and how?
By Wendy.Hu

Yes, the above all you mentioned can be finished by an Arduino sketch. The following code is used for buliding connection between two ble devices:
Code: Select all
void setup() {

void loop() {
  // put your main code here, to run repeatedly:
     int num=1;

Code: Select all
int a=0;
void setup() {
    Serial.begin(115200);               //initial the Serial

void loop()

And there is a link about data sending, maybe you can make a reference:

Then you can edit the code again according to your own requirements.

BLUNO NANO UUID that is a published article from the year 2016 with the proper range of the stories. The demo link is given here with the proper sort of securing the Bestessays with the more kind of the great information with the BLE products.
