bluez

I have a wider range question here, so if someone could point me to a doc or article that could explain this, that would suffice. Needless to say, a days worth of googling has gotten me nowhere, and I could use a helping hand. I am connecting to a BeagleBoard with BlueZ 5.9, and my intent is to: Create a Gatt server, Load it up with some writeable attributes, and Advertise that server to connect to an android device. I've created the Android app that will connect and operate as the central, rendering 3 basically complete. I don't know how the commands - the literal things to type - to initiate

Goal I am developping a simple device running Linux. It is BLE capable, and I am currently using bluez 5.8. I want to trigger an action on this device using an iPhone. What already works: I can make the iPhone "see" the device. The iPhone also connects to the device. I setup the bluetooth device like this on linux (thanks to this question ): # activate bluetooth hciconfig hci0 up # set advertise data: "hello world" hcitool -i hci0 cmd 0x08 0x0008 48 45 4c 4c 4f 57 4f 52 4c 44 # start advertising as connectable hciconfig hci0 leadv 0 The iOS code is straightforward: - (int) scanForPeripherals {

I would like to know if there is a way to set up a gatt server from the Linux command line. I know that the BlueZ gatttool command allows you to act as a gatt client and interrogate a remote gatt server, however, I do not think that this tool can be used to set up a server. What I want to achieve is a gatt server, created from the command line , and can be interrogated by any central device (e.g. iOS or Android device) to connect to the GATT server, discover the services and characteristics, and manipulate the data in the characteristics. Example: Gatt Server with 1 service which contains 3

I purchased a FitBit zip. This device uses Bluetooth 4.0 LE. I would like to at least connect to it via bluez. If that is successful I want to see how much of the protocol I can figure out. I am using a Lenovo P500 Ideapad which has integrated support for Bluetooth 4.0. It seems to work (kind of) When I do: hcitool lescan I am able to find the device's bluetooth address, which (though potentially irrelevant) is: CF:D9:24:DB:F4:7B Now, I read in another question: Bluetooth Low Energy: listening for notifications/indications in linux that I can listen for notifications and other protocol

I'm programming in BlueZ on my Raspberry Pi with an USB Bluetooth dongle. I need to be able to programmatically connect to an Arduino BT, the problem is that the Bluetooth module of the Arduino is still using legacy pairing so whenever I try to open a socket to the device I get a Permission Denied . How do I send along a PIN to complete the pairing request through BlueZ? You might want to check out the main.c file in the client folder of the most recent Bluez source code. It's the source code for the bluetoothctl tool. Run it too. The source code shows exactly how they use GDBus, including

I am working on using the Bluetooth low energy modem with Linux. I am using the command line option for that i.e. hcitool . I am able to the find the devices using the command: $ hcitool scan It is working fine for me, also I am able to broadcast my device using : sudo hciconfig hci0 leadv It is also working fine. But I want to add the services and characteristic to the modem device which can be detected by other device. I have tried sdptool add but it is not working for me. Does anyone know how to add the services and characteristics to the peripheral using the command line tools in ubuntu?

I have a linux computer broadcasting a BLE advertisement using the following commands: sudo hciconfig hci0 up sudo hcitool -i hci0 cmd 0x08 0x0008 1e 02 01 1a 1a ff 4c 00 02 15 e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 00 00 00 00 c5 00 00 00 00 00 00 00 00 00 00 00 00 00 sudo hciconfig hci0 leadv 3 This works well but the computer only broadcasts its bluetooth advertisement once a second. I would like to increase this frequency to 10 times per second or more. Is there a way to increase advertising frequency in BlueZ? Or is once per second the standard and unchangeable? I'm happy to do
