tongo / ble-java Goto Github PK

I create an application, call start() and then stop(), but the java runtime keeps running.

We are configuring our services in the following way.

We are able to connect to the device through app but whatever services we are configuring is not being detected by the ble scanner app on my phone.
Ble scanner output is like

If you could share more information regarding how to configure Services and Characteristics, it would be a great help.

Hello,

I have the same problem #8. But nothing works for me. I tried, after successful build, just run the ExampleMain.java in test/java. I have all dependencies and also checked the java library path, unix-java is also here. I tried it on two different VMs with the same result. Am I supposed to run this ble-java differently?

Thanks!

Hello! How to set the broadcase name.

This can be used to connect to other devices, and watch values ?

To better handle DBus exportObject exception we should provide Path to the exported object on the error.

example stacktrace doesn't define what is already exported.

org.freedesktop.dbus.exceptions.DBusException: Object already exported

	at it.tangodev.ble.BleApplication.export(BleApplication.java:230)
	at it.tangodev.ble.BleApplication.start(BleApplication.java:94)

I will add PR for this, since I need this at my usage.

Is there any way we can set EIR data for our ble peripheral?

Hello,
Thank you for this library, that has been single one that worked in my java code.

I found it today that putting anything into ManufacturerData isn't visible on discovery.

like this:

advertisement.setManufacturerData(mapOf(0xffa0 to 0x0001020304))

Do you have example where Manufacturer data works? Maybe I forgot about something - like advertisement type?

Under iOS

In the MainExample, everything is working fine except the BleApplicationListener. deviceDisconnected and deviceConnected are never called even though I succesfully connect and disconnect with nRFconnect.

Rasbian-Lite Buster on RaspberryPi 4.

Working fine with an Android as a client...

As mentioned we installed libdbus-java on pi
command
sudo apt-get install libdbus-java

BLUEZ version 5.47 installed

Compiled the source but when we execute we get below error

Are we missing something here?
