Hi, I have my EEG-SMT board connected to a raspberry pi board and my goal is to have the pi board send brainwave data to BrainBay on my laptop wirelessly by NeuroServer. So I ran modeegdriver on the pi board with nsd running on my laptop. And on BrainBay, the TCP-receiver is successfully connected to localhost and the status shows that it is reading packets.

However, the output of oscilloscope is just 0. I saw there is a lost packet counts, it that the issue? And I am pretty sure that the EEG board is working since BrainBay can show some brain wave signals when the EEG board is connected with my laptop directly with the USB cable.

Here is my screenshot:

Commands I used on Raspberry Pi:

1. sudo ssty -F /dev/ttyUSB0 -icrnl -ixon -echoctl -echoke
(to fix the error of serial packet sync error -- missed window. Reference: https://www.olimex.com/forum/index.php?topic=3394.0)

2. sudo modeegdriver -d /dev/ttyUSB0 [ip address of my laptop]

Anyone knows how to fix the 0 reading issue?
Thanks in advance!
