Hi @Pradeep ,
First, I’m not super familiar with Python, so forgive me if I’m overlooking something obvious…
If I’m reading the stack trace correctly, it is simply suggesting that the Notecard is unresponsive.
You reported the following connection between the Notecard and the M5UnitCam V2:
Wiring Connection:
NoteCard | UnitCam V2
1.TX ------------>RX
2.RX------------->TX
In order for the Notecard, or any device, to interpret logic-level signals there must be a common ground between the two devices. So in this case, your hardware connection should require 3 wires as follows:
Wiring Connection:
NoteCard | UnitCam V2
1.TX ------------>RX
2.RX------------->TX
3.GND---------->GND
If you already have a common ground, but forgot to mention it, please let us know, so we can continue to explore your problem.
Best,
Zak
