[Bug]: DFrobot Lark Sensor No data to be seen via I2C #5560
Comments

do you have a bootup log where the i2c scanner is running? |
The Lark is not visible in the serial monitor. The only thing that was detected on 0x40 is the also installed INA219. I also tried to uninstall this and only install the Lark. However, it is not displayed there. I will submit a copy of the output during the boot. |

@caveman99 this is indeed not working, my lark no longer is detected. |
|
Yes, there seems to be a problem. Is there any information about it yet? |
|
i changed the detection code to not mistake it for the RAK GPS. I don't have a lark myself, i can test with @MALAONE1 directly. |
|
umm, you have an INA219 at the same board? that won't work. we only support one device per I2C id on the same bus. |

Description
I have a DFrobot Lark sensor connected to I2C with a RAK 4631 with RAK 19003. The Lark writes all weather data to the internal memory. I2C communication is set in the config, the green LED lights up on the Lark which means that I2C is activated, all cables have been checked several times for the I2C interface to the RAK. According to the serial monitor, the LARK is not recognized.
