Unable to connect with Application Board !

[chi86]

Hi, I installed a breakout board with the bme688 on my raspberry pi 4. When I tried to run the forced_mode example, the following message comes up:

Unable to connect with Application Board !

1. Check if the board is connected and powered on.
2. Check if Application Board USB driver is installed.
3. Check if board is in use by another application. (Insufficient permissions to access USB)

The compilation finished without error, and the "i2cdetect -y 1": 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- 77

That the id "77" is up.

Any idea what I forgot or did wrong?

I too am stuck on this. But have you had any success with the python library? Using the python library I know that my sensor works. Have you managed to make any progress with overcoming that Application Board error?

The error code I get is COINES_E_DEVICE_NOT_FOUND (-5) when bme68x_interface_init is called.
