OpenBCI is hardly used for medical & research applications. It is little developed for this purpose. Altough it has the potential for it as shown for instance in this paper:

And it seems also be possible to add multiple OpenBCI Cyton boards over the nRF Connect on my Android app, as shown by Blake Calgary, Alberta, Canada:
«solved:
Hey everyone, just an update. There is a field to enter the MAC address. I had to download
nRF Connect on my Android to discover the MAC address for each Ganglion, but once I put the MAC address in the settings ( without all the : : : ) they now pair only with the selected Ganglion»

More than 16 channels cannot be sampled at exactly the same time with this method, which is necessary to get all the parameters, such as phase, coherence, etc. This would be required for a professional device for medical and research applications.
But we can eventually use a 16 channel OpenBCI system, and trying to add another Ganglion or Cyton board for other physiolocial paramaters, such as EEG, MEG, and spirometers. These parameters are not so critical as far as timing is concerned.
For these kind of experiments, OpenBCI can be very helpful. And we think also it is possible to add a Wifi shield which is sold on eBay and Aliexpress to the OpenBCI system to get faster transmission. But we have to repair the WIFI shield.
For doing some experiments for someone wo wants to build a device OpenBCI is interesting. But if we are interested on the long-term in device building, we should have a look at InfluxDB systems as soon as possible:
