Hello! i am working with nrf5-ble-mpu-data-ready-interrupts example from github, I defined twi, could compile it without errors. But the case it, it doesn't advertise and i don't see it in any applications. I am using keil uvision v5, sdk14.2 and nrf52840 DK(pca10056), mpu 9255. Other example without ble worked fine. What might be the problem? thank you in advance.
