Wireless signal returned is either 0.0 or 1.0

[landret]

Hi, the wireless signal should range between 0.0 and 1.0. However, either 0.0 or 1.0 is returned by my headsets, nothing between. Test done with

• EPOC+ S/N 4A2C01C7 firmware 0x634
• Insight v1.0 S/N 5968367B firmware 0x5014

@landret , how do you get wireless signal from cortex ? did you get correct order from data stream ?

[landret]

@nguoithichkhampha Example for the insight headset: the order is : ["Battery","Signal",["AF3","T7","Pz","T8","AF4","OVERALL"],"BatteryPercent"]

Example of data sample I receive for the "dev" data stream (I am not wearing the headset here so the sensors signal quality is bad) :

{"dev":[3,0.0,[0,0,0,1,0,0],59],"sid":"09ff2962-dc7b-40f6-843e-c98691af56d9","time":1680252416.4949}

or

{"dev":[3,1.0,[0,1,0,0,0,0],64],"sid":"09ff2962-dc7b-40f6-843e-c98691af56d9","time":1680252371.4733}

For the wireless signal, the Json data sample shows either 0.0 or 1.0 when I move the headset away from the dongle.

@landret Can you try to record data and send me an example file ? how long you see the wireless signal = 0.0. in theory, wireless signal = 0.0 mean very bad signal.

@nguoithichkhampha Here is a recording.
