How Pair & Connect Via Bluetooth | Building a Bluetooth Chat App for Android | Part 2

Congrats for 100k subs Philipp!! 😊 Still remember I'd subscribed back when the channel name was Android Devs with 3k subscribers :) The content quality has reached completely next level now 🔥🔥

Thanks a ton!

Hi, could you please show an example of how to implement Bluetooth or BLE alongside of navigation? Because it seems to be impossible to properly share bluetooth devices/advertisements across multiple composables with navigation. None of the Bluetooth components are parcelable.

Hey Philipp, a BLE Tutorial with pairing, send and receive data would be greate. Gteetings from Dortmund

[@setteroid]

please make video about NFC

Please do video about new media3 lib mediaSessionService!!!

Hello Philip, I would like to ask if its possiable to build android aplication that can scan BLE signal on background and if the app detected the right signal (UUID) than send data to the server and also show notification. Thank you a lot for the answer

Thanks for this playlist!

Isn't the while loop with the variable shouldLoop redundant here? I mean if we want to close the server after establishing a connection, then this ruins the purpose since the loop will continue and accept subsequent incoming connections afterwards. So it seems like either the close() call is redundant or the loop is.

Have had a "pleasure" working with BLE for quite some time... Unfortunately no matter how good you code is the BLE stack is HORRBILE accros manufactures. Tons of unsolvable bugs related to hardware layers. I'll never work with BLE product based companies any time soon :)

[@ChrisAthanas]

Im glad im not alone in this experience of BLE. Its a rather overcomplicated and strangely-named API, no wonder so many products get it wrong or implemented improperly. The API's for Android abstract a bit of the BLE zaniness, but its still frustrating that there isnt more cohesion among the device manufacturers. Looks like we will have to wait for BLE-2

Can you make a lecture on controlling the Arduino sensor through Bluetooth interworking?

[@souptiknath4668]

Thanks for the tutorial. Can we implement the same thing with wifi?

[@ChrisAthanas]

Like peer-to-peer comms over wifi?

[@souptiknath4668]

@@ChrisAthanas Yes the same chat functionality

Hey philip i just want to ask how to become the best developer do I have to develop more apps watch tutorials or stay updated with new releases I am confused I could really use your suggestion.

[@luisjesuslopezaguilera432]

Hello Philipp. First of all, congratulations for your videos. They are wonderful. I ask you for help. I have an app that plays streaming audio from the internet, selecting several stations. My problem is that I would like, from the hands-free of the car, I can change the station, as if it were an mp3 player. I can't get any of the tutorials on youtube to work for me. Could you please help me? Thank you.

[@burakbektas740]

I downloaded the latest version of the application on github to my phone, but when I press start scan, it does not scan and the server scan part does not appear.

[@jawedsarmani5467]

Could you please tell where u define onClick method that is used in the Device.kt file in last portion.

[@ramdaspolekar4717]

Thanks for the great tutorial. Just one thing, How to get UUID which you provided hard-coded? I don't want random one.

[@PhilippLackner]

But that's the whole point of it to be able that another device with your app can connect to it

[@ChrisAthanas]

Are you asking about the individual phone ID? Like the IMEI number from the cell phone sim? Or MAC address? The UUID is the static id for the chat service running on one (or both) of the phones. You can generate this UUID in any way you like, including using kotlin, or just making one up. You just want an ID that doesnt conflict with any other service that another app may be using.

[@412hack8]

Hello Philipp, I have a problems working with the implementation you give in this video. The problem is that when I start server on one device and then scann from another, some scanned devices doesn't have name in list. only addresses. However, paired devices have everything including names. Alos , pairing process only workeds from paired devices. I made a reserch. and found that others also have faced this problem but there is no valid sollution. please if you have any solution , tell me. thanks in advance

[@drackon1995]

Excelent Videos, But How can i connect and disconnect a bluetooth device without shared data?

[@ramdaspolekar4717]

I want to find correct UUID of Bluetooth device. How to find correct UUID?

[@ChrisAthanas]

Do you mean the IMEI number?

[@ramdaspolekar4717]

@@ChrisAthanas No, when we want to connect with device, we need to create socket which needs UUID for communication. In video Philip provided hard-coded UUID in companion block.

[@ChrisAthanas]

@@ramdaspolekar4717 ah ok He mentions that you can pick any number you like for the uuid You can use Kotlin to generate one It just needs to be unique for the chat service that is being served.

[@ramdaspolekar4717]

@@ChrisAthanas I also tried multiple UUID's from stack overflow. But my case it didn't work.
