Using neurofeedback on app while connecting to laptop to record raw EEG output


I am a researcher wanting to study the effects of neurofeedback. I want to be able to use the app to play the neurofeedback while using the headband while simultaneously recording the raw EEG output on my laptop. But when I try to connect to both devices via bluetooth it will only connect to one device at a time. Is there away around this or is there a way to view the raw EEG output on my computer after having completed the session on the app? Please Help!
Thank you!
