Hi there,
I'm trying to build the Beacon source code with GCC toolchain on Ubuntu, but it's not working on Beacon Kit, there is no any response from the kit. But I tried...
I was wanting to use a nRF24L01 with a breadboard but its pin-out didn't allow it. A solution then occurred to me based on parts at hand. I wrote it up with instructions and...
Hi,
I'm trying to see what the communication range would be for different transmission powers. I set the transmission power to 0 dBm, and observe that I can still receive...
I'm currently trying to make my application enter into sleep mode, after some search , I found that this function can be used to reduce the power while the chip is in the...
Looking over documentation and the forums, it appears that the softdevice is not meant to be used with an application that uses an RTOS. I say this primarily because disabling...

I've got this issue when the connection is not very stable...
An arduino board is to much for my project. I only need the interface for the NRF8001 and only 2 or three extra IO pins.
Can I use the ATTINY25 and what is teh proper connection...
This question pertains to the nRF24LE1. I've programmed a MCU before with a relatively simple program, but never one with wireless transmission, so please forgive the naivete...
Hi,
for Mass Production I have to flash 24 nRF51822 in parallel.
Did Anybody something similar before? What mass production programming equipment have you used?
Thanks...
