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 using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
An external PA/LNA is used to extend range of nRF51822, and S110 is used for BLE, How to switch between PA and LNA? and how to disable PA/LNA when there isn't transceiving...
Hi...
Can anybody help me to run ble_peripheral example (ble_app_hrs for S130). I have build and load the code successfully but cant see the advertisement. But while debugging...
I am working with the nRF8001, and I'd like to create a services.h file that will let me broadcast battery level and as well as allow temperature to be read by a peer.

Hi All,
We are trying find a way to upgrade nrf51822 in the field post initial release.
I read the following posts
( devzone.nordicsemi.com/.../)

My board requires P0.9 and P0.10 to operate as GPIO pins. On the NRF52 these pins share the function with the NFC antenna. How do I make them function as GPIO pins?
I know...
Hi,
I just finished compiling my code for the nrf51 to take ADC measurements and send the hex values over ble tuart o my iphone. Now I want to see if I can send that data...
Hi, i know maybe this question was asked before, but i have a particulary issue.
I have 2 devices connected through BLE. Just when them get connected i need to send a byte...
Hello!
I need to read a string from UART, there's code below:
unsigned char GetChar(void)
{
while(!RI)
;
RI = 0;
return SBUF;
}
int Readfstr(void)
{
char...

I'm trying to use BLE library for python to communicate with one Nordic nrf51844 chipset. Because one characteristic is notification enabled, I need to enable notification...
Does there exist a white paper describing some typical PPI use cases with coding examples? The only one I've found is the peripheral/gpiote example and it is severely lacking...
Updates are moved to the end of the question
I created a modified version of pca10028.h and boards.h and have preprocessors changed so that the following new config is...
I example test ble_central and ble_peripheral of ble_app_uart.
Radio TX and RX test is OK.
It confirmed the data communications relating to uart_event_handler function....
I'm trying to get a time stamp using app_timer_cnt_get(&ticks), but the ticks always equals 0. And I have called APP_TIMER_INIT() to init the app timer. I have no idea why...
Hi everyone, I have been given a nRF51-DK board and I should use it to send data retreived from a sensor to it through Arduino, to finally receive it in my cell phone. I am...
Hello everyone,
I'm brand-new here. I have developed quite a bit of software on desktop PC's, but this is my first experience with embedded programming. A few weeks ago...
