Documentation for Fluoride bluetooth stack - bluetooth

I'm working on BLE using Fluoride stack which is open-source. Is there any documentation or any notes that would help me to understand the architecture of Fluoride stack? Any help regarding this would be appreciated.

Not really. It was called Bluedroid before and was written by Broadcom before it was taken over by Google for Android. You have some info at https://source.android.com/devices/bluetooth of the overall structure, but documentation is lacking. Reading the source code is the best idea I can give.
If there is any particular part you're interested in (GATT, SMP, L2CAP, connection establishment, Java layer) etc, feel free to ask.

GPS Device and Node implementation

I want to track the live location of a truck.
Is it possible to interface a tracking device with nodejs? if yes, what kind of tracking device is compatible with node?
And links to helpful blog post or any resource that would guide me accomplish this would be really appreciated.
I love using Johnny-Five to interface nodejs with hardware. Here is a link to their examples using some common gps modules. http://johnny-five.io/api/gps/

Nrf51822 programming for noobs

I want to use a bluetoothmodul like this Waveshare Core51822 to send data to a raspberry. I want to use the SPI on the bluetooth modul but i dont have a plan how to configure that.
What do i need?
Thanks
The SPI and BLE are all documented extensively at http://infocenter.nordicsemi.com/, including examples, specifications, and an API.
In the future, you should give much more information about your situation. For instance, what platform/IDE are you using to develop? If your module is compatible, you would probably be best off using ARM's mbed compiler (https://os.mbed.com).

VoIP android studio

Hi I'm not very good with coding but I'm trying to learn as much as I can. I've been looking for tutorials on how to create an internet call app on android studio. So far I haven't found any. If anyone knows a process that could guide me I would very much appreciate it.
You can use android's own implementation
Session Initiation Protocol
from docs
Android provides an API that supports the Session Initiation Protocol
(SIP). This lets you add SIP-based internet telephony features to your
applications. Android includes a full SIP protocol stack and
integrated call management services that let applications easily set
up outgoing and incoming voice calls, without having to manage
sessions, transport-level communication, or audio record or playback
directly.
or other third-party libraries like following.

Happy Coding :)

what is the difference between chanctx based drivers and non-chanctx based drivers?

I am a newbie to linux device drivers. I have been writing driver for a WLAN device. While registering callbacks with mac80211, I found a few callbacks (OPTIONAL ones) regarding channel contexts. I just dont understand how they work?
Please go through this link to understand the significance of those structures.

Qt Bluetooth with Linux

I'm trying to setup a bluetooth server for one device with Qt and can't figure out how to use QDbus and bluez.
The device is going to send strings. The two are already paired.
Your question is quite generic, what is your problem exactly?
A very good resource to start understanding bluetooth protocol and its programming model in C is http://www.btessentials.com/
The original resource that has reorganised into the mentioned book is available online here Once you will have a fair understanding of the basic you could seriously think to wrap everything with Qt :)
