It is deliverd as an msi file with (as far as I have noticed) no support for specifying...
Is there anything preventing anyone from uploading the tinyest image that simply dumps the entire ROM content on the UART?
This would sort of circumvent the HW locking...
Hello,
I use nRF51822 for my project and I would like to purchase some BLE packet sniffer. Does anyone recommend any sniffer? My purpose for that is debugging and check transaction...
On PCB layouts I often see that the HF xtal is oriented at 45 degrees relative to the orientation of the 51x chip (that is to say the edges of the the xtal and 51x chips are...
Hello Nordic expert,
Regarding the antenna load impedance, I can find the data in nRF24L01+ datasheet and it is 15ohm +j88ohm.
But I can not find the antenna load impedance...
