Hello,
I have some strange behaviour with the BME280.
At random moments the BME280 pulls the SCL line low, only a power cycle of the BME280 fixes the problem.
The problem is not directly reproducable and occurs at random times (after 8 to 1000+ sensor readouts).
I2C specifications:
- 1.80V supply
- 4700R I2C pull-up resistors (230ns rise time to 80%/VCC)
- Fast mode (400kHz)
- I2C master is a i.MX7 and is connected to I2C channel 0 (LPI2C0_SCL and LPI2C0_SDA)
- No other slaves are connected to the bus
Is this known behavior?
if yes, how can this behavior be avoided?
Best regards,
Maarten
