Hi, I have two problems on two differents Mangoh Green boards. Both with the bleSensorInterface demo and bluetoothUtil. On the first one I was able to install the driver for the WL18XX bluetooth module, I started bluetoothUtil without problems. But when I start **hcitool scan** the board detects all the bt devices around it but not the sensorTag, even if my phone detect the sensorTag. Even if I config the MAC addres for bleSensorInterface manually bleSensorInterface can’t find the sensorTag. On the second one, when I launch bluetoothUtil it stop working after **hciattach /dev/ttyHS texas 115200 flow** the output is > Wanted to write 4 bytes, could only write 0. Stop > Can’t initialize device: Success The device hci0 is listed but can’t do anything. (I had the same issue with the first board but it disapear after a reboot, unfortunatly rebooting don’t change anything on the second board) Do you have any idea why ? Thank’s ---

Hi, May I ask you what type of machine you used to install the driver for WL18XX bluetooth module? I am using Ubuntu16.04.1 with 4 core and 8GB ram VM and “make image\_bin” took me almost 2 days. But I encounter issues when trying to start menuconfig. Any help from you will be appreciated. Thanks! I am following instructions from: [https://github.com/mangOH/mangOH/wiki/Bluetooth-WL18xx-driver-for-mangOH](https://github.com/mangOH/mangOH/wiki/Bluetooth-WL18xx-driver-for-mangOH) ---

I used, ubuntu 16.04.2 with 4 core and 16gb RAM (installed not vm), it took me 1 hour to compile, I used the same tutorial as you. If you have a thread where I could help you it would be great. I don’t want to mix things here 😉 ---

thanks for the fast response. I think it could be permission issue and I think I will try it on a real machine as well. Sry to mix up here and here is my post: [WiFi/Bluetooth Demo release](http://mangoh.discourse.group/t/wifi-bluetooth-demo-release/86/26?u=wavefront_yk) ---
