@yutaide can you try putting something like a 4.7k-10k pull-up resistor on each of the i2c wires. It did not look like your breakout board included them and the stm32 GPIO configuration we use does not provide any pull-up as this is usually external. This would explain the error you are seeing. Do you have a link to the breakout you are using? -- This is an automated message from the Apache Git Service.
