Hi,
We are using the nRF905 device in an application where it needs to switch between auto-retransmitting and sending single packets, due to it communicating with several...
Hi everyone, quick question.
I'm using the nrf_drv_timer library (from SDK 15.0.0_a53641a) to count the RTT between connection events packet Tx/Rx, however, I get this undeclared...
Hi
The 840 datasheet (page 90) states that the HFINT tolerance is +/-1.5% typical and +/-8% max.
Under normal operation, the HFINT is running and so if the device (like...
I was beyond excited to see all the support Nordic was providing to the mbedOS project.
All of a sudden it disappeared.
If not supporting mbed the alternatives would...
Hello,
We have an nrf51822 system where disconnecting the battery is problematic, and the sharing of the reset line between SWD and reset function has been a real source...
