Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

HI all:
I am using the nrf24le1.And i confuse about the recive and transmission address in rf transceiver.
What do we use the address to do usually.It will be wonderful...
Copy nrf51.cdb to "C:\Keil\UV4"
Copy nrf51xxx.flm to "C:\Keil\ARM\Flash"
Set the keil project-device to nRF51822(data base : Nordic nRF Series Devices)
This is...
Hi
Is there a documentation of the nRF51822 sniffer interface? e.g. communication structure, command format, captured messages structure etc?
Thanks

I'm unable to write my application code to the flash of an NRF51922 (QFAACAA). NRF Studio will let me flash the hex file but it fails verification. If I try programming in...
I have a question, can nRF51822 operate in regular Bluetooth mode like a Bluetooth 2.1 device?
If answer is no then, is there any product from Nordic that operate as Classic...
Hi developers,
I've finally got the nrf51822 working and advertising a good signal to the dongle. :)
After doing all the steps in the NAN-36 pdf-file I hoped that pressing...
Hi all,
I'm using Timer2 while having the SD enabled, and I'm having some problems. I don't seem to be able to reliably set the periodicity of the timer. No matter what I...
I've spent quite a while getting Eclipse on Mac OSX working. I started with the original makefile but have come up with, finally, a working native Eclipse build which does...
Hi all,
I have an external dongle (Bluegiga) that is scanning for BLE devices.
My problem is this: all the BLE devices in my room are showed correctly except my nRF51822...
Is there a link where I can find all sources of applications for NRF51822 corresponding at iOS App "nRF Utility" (with explanations of use of both systems)?
Thanks for...
