to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...

Hi,
I'm creating a project on nRF51822 chip and I have a problem with disconnection. In my program I want to disconnect with master after some time e.g. 30 seconds. I'm using...
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...
I 'm developing using a nrf51822
and use 256kb rom 16kb ram.
I met ram overflow frequently.
so,I want to calculate the ram size at the map file.
could you explain how...
Hi,
We are using the nRF905 device in an application where it needs to switch between auto-retransmitting and sending single packets, due to it communicating with several...
