Hi William, It is great, mostly thanks to you! Yes, I can put it on a GitHub repository. I am under a bit of time pressure now, so maybe in a week. Thanks, Max

Hi William, Yes, it worked!!! I use Ubuntu. I put the "nrfutil_linux" file in the "~/Desktop/arduino-1.8.7/portable/packages/Simblee/hardware/Simblee/1.1.4" folder. In the same folder, I modified "platform.txt" by comparing the one for…

Hi William, Many thanks again for your support! Your responsiveness is amazing! I added the nrfutil_linux to the correct folder and was able to build a HEX file. I had to go to a meeting and am now just getting back to it. Best regard…

Hi William, Is AJ Keller still involved? He seems to have vanished. His Twitter account and Push The World LLC don't exist anymore. The last comment from him on Gitter (https://gitter.im/OpenBCI/OpenBCI_NodeJS?utm_source=badge&utm_medium=…

Hi William, Thanks for your quick response. You have been incredibly helpful over the last few weeks! We actually need a sampling rate of a multiple of 125 Hz, thus AJ's solution may work! Best regards, Max

Hi Florian and William, Great news: I ran the Ganglion connected to my Amazon (Android) tablet for 10 hours with NO lost packets! I used a modified version of the demo app: https://github.com/Brain-Hero/GanglionAndroidBluetooth/releases/tag/…

Hi William, Good to know. The battery level is not too important now, but a nice-to-have feature at some point. Thanks, Max
-
Hi Florian and William, Is there a way to poll the Ganglion for the battery level? I don't see a way to do this in either the code or the documentation. Thanks, Max

Hi William and Florian, I added the following to 'BluetoothLeService.java': public static int getTotalPackets() { return totalPackets; } public static int getLostPackets() { return lostPackets; } public static double getPacketLossPercent() {…
-
Hi William, I was thinking of the very same thing! I am learning Florian's code to see how to at least keep a running count of dropped packets. I have used MPAndroidChart (https://github.com/PhilJay/MPAndroidChart) in another application, f…

Hi Florian, I am working with the code now: https://github.com/Brain-Hero/GanglionAndroidBluetooth/releases/tag/v1.0.0-beta I noticed in BluetoothLeService.java that there were line/comments such as this: mBluetoothAdapter.startLeScan(mLeS…

Hi William, Ah, yes. I should have remember the bandwidth limitations for higher sampling rate. I think that there is an error in the documentation of the web-page you referenced, it mentioned 250 Hz, it looks like that they cut-and-pasted …

Hi Florian, I spent a short time trying to add the library, but on luck. I suppose I could adapt the source code in the library as a last resort. Thanks, Max
-
Hi Florian and William, I am integrating the repo now. I am having a little problem, with which maybe you could help. I am adding the dependency (implementation 'com.github.Brain-Hero:GanglionAndroidBluetooth:Tag') to the 'build.gradle' app…

Hi Florian and William, Great news! My Ganglion board has arrived. So far all looks great. I'm working with the OpenBCI_GUI now. In a few days I'll see if I can connect to my Android application. I'll keep you posted. Many Thanks!!! M…

Hi Florian and William, My partners and I am going to order the Ganglion! I am going on vacation now, but I'll study more if I have spare time during vacation. I look forward to using the Ganglion when I am back in town. Many thanks to …

Hi Florian, I haven't worked with Unity, so I plead ignorance there. But if you go from 6% packet loss with the Java library to 20% with Unity (same platform?), could it, as you say, simply be a CPU loading? Maybe increasing the thread priorit…
-
Hi William, I'll likely order the board soon. I am discussing it with my partners-in-crime. I'll keep you and the forum updated. Thanks, Max
-
Hi William, Thanks again for all your insights and responses. I am getting the impression that packet-loss or lack thereof is dependent on the amount of buffering in the BLE device and the responsiveness of the application/OS combination. I…
-
Hi William, I must confess, I don't see the advantage of using the Muse packet format, unless someone does not want to need to change their, e.g., Android application. I'd think Muse would be happy if someone's mobile application used their pro…
-
Hi William, * As you imply, it is a question of the throughput from the Ganglion to the Android device via BLE. Very roughly, the Muse data-packet size is 32 bytes (four Java doubles), so 4 x 8 x 256 = 8192 bytes/second. But I don't know if Mu…

Hi William, I used the Muse headband. It is a great device, but does not quite suit my purposes. I was able to stream four channels with the Muse via BLE to an Android tablet with no packet loss. I then was experimenting with the Texas Instru…

Thanks, William. I shall study the information you supplied.
