Hello,
We are trying to evaluate the HomeKit SDK with our nRF52832 BLE modules. The "Lock(static)" sample application doesn't work with Apple 'Home' App on iPhone 8+. The...
I'm currently evaluating different platforms, that run on the nrf52832 soc, like Nordic Semiconductors own firmware, as well as Zephyr, myNewt and mBed. As you guys from ...
Dear sirs
Good evening !
I´m using the RF24.h library in order to develop a system that comunicates in peer-to-peer mode.
When I transmit 3 bytes towards a receiver...
I'm hoping someone can tell me if I'm on the right track. Do I understand correctly that on an nrf51, the LPCOMP can be configured to wake the processor on an analog input...
Hello,
I was wondering how is calcualted or read on the Thingy firmware the variable w for the quaternion used in the Gyroscope readings.
Looking into m_motion.c in the...
The power data of lfclk is measured under the same hardware and software conditions. When we used two model chips, we found a difference of 1 microamps for the value of the...
hi, I am trying to make buttonless dfu working, but I am not sure how to do that. I am using SDK 14.2.0 with nrf52832. right now, the ble dfu example works. and I found in...
