NodeMCU/Linux aims to target following hardware running a Debian-based Linux:

• Raspberry Pi series (like Raspberry Pi 3, Raspberry Pi Zero) running Raspbian
• Orange Pi series (like Orange Pi Zero, Orange Pi Lite, etc) running Armbian
• NanoPi series (like NanoPi NEO, etc) running Armbian

detailed list of supported devices will be published as soon gpio and i2c modules are more complete and tested.

Insert your micro SD card imaged with Armbian into the micro SD slot on the Orange Pi Zero. (Optional) Connect your Orange Pi Zero using an Ethernet cable to your router. Connect three jumper cables between your USB-to-Serial converter and the Orange Pi Zero. Mac address-table static. Adds static entries to the MAC address table or configures a static MAC address with IGMP snooping disabled for that address. Show mac address-table aging-time. Displays information about the time-out values for the MAC address table. Show mac address-table count. Displays the number of entries currently in the MAC.

• majority of the modules are meant to be implemented with Lua itself and external modules via luarocks
• if hardware-near implementation is needed:
  • Lua 5.1 and luaffifb module https://github.com/facebookarchive/luaffifb
  • LuaNode has async IO infrastructure with ffi support (currently used)
  • LuaJIT FFI: http://luajit.org/ext_ffi.html interfacing C functions and structures (parses string to extract struct information) NOTE: currently luajit is disregarded, but lua5.1 is used
• ...

Following modules are aimed to implement NodeMCU/Linux mainly based on the NodeMCU/ESP8266 API and partially on NodeMCU/ESP32 API:

I'm using Mint 15 w/ Cinnamon.

I bought a set of bluetooth speakers and I'm trying to connect to them via terminal. Via the GUI I can see them normally and I am connected to them. I want to make a small script so every time they are visible I would connect to them automatically.

I am trying to scan them with:

hcitool scan

But I get

Scanning...

and after a few seconds the process dies.

The same thing with hidd --search.

If I run hciconfig scan I get:

I suppose that is just saying my bluetooth address and that it is turned on.

As I said already, via the normal User Interface, I can see the speakers and I am connected to them, but through terminal I get nothing.

Actually it is quite funny that hcitool scan isn't finding anything since my speakers are connected and every time I run the command the sound from the speakers breaks for a couple of seconds.

I managed to do so via bluez-tools:

sudo apt-get install bluez-tools

List of devices to get the MAC address of my device:

bt-device -l

and successfully connect to it:

bt-audio -c 01:02:03:04:05:06

Keep in mind that the bt-audio feature is being reimplemented for newer versions.

I did to sudo apt-get install bluez-tools, because I did use it at some point.

After being able to find the device from hcitool scan,I ran bluez-simple-agent hci0 X where X is the mac address of the device I was adding. This created the connection to the device.

Then I ran hciconfig scan and it seems to have automatically started the connection.

I know this is kinda late but I was playing with this command hcitool and I'd like to point out something that I noted which solves your issue of doing a scan and the process 'just dying'. The thing is the scan only works if the devices are unpaired. In your case, you say you can see the speakers are connected on the GUI which means they've already been paired...hence the scan returns nothing.

I'm working on how to pair/connect devices with the same tool although I can see you've been given other options. I'll update my answer as soon as I manage.

To do it with the built-in utils, you can follow this slightly more manual process using bluetoothctl.

The posts in this Github issue suggest a way to script it, but that did not work for me since I needed to manually wait for the scan to yield results.

I have the following installed in Debian 9.

I have already paired my Bluetooth headphones to a USB Bluetooth adapter on my desktop using the GUI application Bluetooth Manager. I have a keyboard shortcut that runs the following two commands: bt-device -c 00:02:5B:01:3C:3B; pacmd set-default-sink bluez_sink.00_02_5B_01_3C_3B.a2dp_sink

1. Connect headphones to the Bluetooth USB adapter. (Use bt-device -l to get the MAC address.)
2. Set Bluetooth audio as the default output. (Use pacmd list-sinks | awk '/index:/ {print $0}; /name:/ {print $0}; /device.description/ {print $0}' to get the correct name.)

This might be a bit late, but I had the exact same problem, with the same output from hciconfig.

However, sudo hcitool lescan did the job for me - maybe it can still help you!
