I am playing with the nRF52-DK preview and I noticed the samples in the 0.9 SDK are set to 32k of RAM. I increased it to 64k as per the chip specification and had no problems...
Hi,
I'm in a situation where I need to get two devices communicating using S110. I am aware that I can send using S110 and I am only referring to small transfer sizes....
Hi,
I meet a very strange situation when I tried to wake up nRF8001 from sleep.
I send 0x05 to nRF8001, it replies me ACI command 0x40 is unkown (0x82).
I have checked...
Greetings,
I recently bought an nRF51 dk and was trying to see how to implement the AVRCP profile to play/pause music on a smartphone.
After some research, am i correct...
I measured the conducted power on the PCA10028 demo board and get ~2dBm out when I set the output power to +4dBm. It appears the PCA10028 is using a discrete balun. Is 2dB...
