Nor I2Cscanner, not Wio Battery example do not finds 0x55 device.
Battery is in Power on state(Green LED is ON).
SCL, SDA signals are correct. Tested with Scope.
What could be done? Is it faulty?
Finally, after 3 weeks of explanations, support agreed that item defective.
I’m having the same issue. Worked the first couple days but now it isn’t detecting anything. I2C doesn’t find any devices. I get the green and yellow leds, no red. Does anyone have any ideas to try?
