Muse 1 only supports standard Bluetooth transmission, and comes to a limit on this transmission patch with 4 channels over Bluetooth. Details can be found in the Mind Monitor forum.
Muse 2 supports BLE, which allows more data to be transferred.
According to the info we have, Emotiv Epoc Flex 32 control box box seem to have only BLE transmission. But does this work at all?
OpenBCI has BLE transmission with up to 16 channels.
But does a 32 channel transmission over BLE work? Is there enough bandwith for this?
Shortly after we became interested in EEG devices with many channels, the Aliexpress 32 channel was available on the market for 600 USD.
Then, the Epoc Flex with 32 ch appeared on the market for 1200 USD. For LSL we need the Emotiv Pro version, which is $89.00/ per month.
The Aliexpress 32 boards needs coding for the interface, and has only a 75 money back warranty. But we ask ourselves, where is the difference between these two 32 channel boards, and are they identical?
Shortly after Emotiv released the 32 channel box, on Aliexpress, only the 32 channel version was available for 1200 USD, the same prize, as the Emotiv Epoc 32 control box.
