Hi Team,
Our customer is using Arduino MKRWiFi1010 that contains BQ24195. According to her, when it gets an error on Reg09, it halts all arduino operations. She is getting the values of 128 and 48. She had reached out to Arduino but was directed to contact us because the device she is reading error codes from is BQ24195. What could be the cause of this error?
Attached are the schematic diagram of MKRWiFi1010 and the source code.
