A new library/toolkit has been built that allows us to invoke the services of an nRF24L01 from a Java environment. Documentation and links to the Github project can be found...
Hi,
I am sending data from Android phone in every 200 ms to nRF8001. But sometimes I found there is a 50 ms or 100 ms delay. It looks like nRF8001 spending some time in...
Hello,
I'm starting a new nRF51 project on mbed for a custom board. I wish to know what is the "cleanest" way to define pinout (what file to edit) ?
Thank you
Hi,
I am trying to run several applications sequentially on the nRF51822.
I have another microcontroller controlling the nRF51822 by SPI.
I init the stack, the services...
Hi, I'm just wondering if there's a reason that the example code is always initializing all structures through functions. Has it something to do with sleep mode and RAM retention...

First of all, let me say that I've read some of the other topics, and I clearly don't belong here haha. I'm not at all knowledgable about electronics and the inner workings...
I wonder if a couple (or three) of your module with PCB antenna as receivers could be used for triangulating the transmitter, could I have some hints about this, or a schetch...
Just putting this here in case anyone else comes across this issue, esb_arm.lib and gzll_arm.lib don't appear to implement the work-around in PAN 18(in the version I tested...
Hello, I would like to know if the adress byte that is transmitted after the preamble is the MSB or LSB.
