Android Question Set ble advertising data

[giada]

Hi,
i need to set ble advertising data, in particular i need to set manufacturer data for 25 bytes:

19 ff ......

i tested ble2peripheral library but some bytes are fixed from the library,

how can i do ?

The BLE peripheral library is built for a specific case and it mostly not customizable.

If you know a bit Java then it shouldn't be too difficult to modify the library and change the advertising data: https://github.com/AnywhereSoftware...wheresoftware/b4a/objects/BlePeripheral2.java

And after i modify the java code how can i use it in my project?

 

[Erel]

You will need to compile it and add it as a library. You can use SLC to compile.

You should post some code with what you are doing. Maybe then, someone can help you!
In the code that Erel posted (https://github.com/AnywhereSoftware...wheresoftware/b4a/objects/BlePeripheral2.java), there is a function already to set Manufacturer Data.

/**
     * Gets or sets the manufacturer specific data that will be advertised.
     *Each item in the map should have a positive int number as the key and an array of bytes as the value.
     */
    public void setManufacturerData(Map Map) {
        manufacturerData.setObject(Map.getObject());
    }
    public Map getManufacturerData() {
        return manufacturerData;
    }

So what happens when you declare something like this:
Private peripheral As BlePeripheral2
and then use
peripheral.ManufacturerData =
with the Map of your manufacturer data.
I haven't used this library so can't help you anymore. Have a look there https://www.b4x.com/android/forum/threads/ble-peripheral-as-ibeacon.105601/#post-661465,
or do a search for "ManufacturerData.
