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,
I am wondering why PSTORAGE_NUM_OF_PAGES is by default set to 2 in the DFU project.
From what I understand the pstorage_raw.c module is used to update bootloader...
In iOS, it is possible for different apps to send data to the same characteristics in the same device by calling retrieveConnectedPeriphrals… Is there a way to identify the...
Hello,
currently, I am trying to get the SPI (master with EasyDMA) to work. I interfaced it with an LED driver IC , which needs some signaling (via GPIO pins) along with...
Hi,

Hi, I have managed to get my nrf51822 DK kit to read LDR sensor values. However the characteristic values are represented as hex on the master control panel and also on the...
Hi,
I'm i'm sniffing the NRF51822 s110, using the Nordic's BLE sniffer (on s120).
The BLE device is in a connection, and do a connection parameter update to a new interval...
Hi All,
I'm trying to update the application firmware of an nRF52 board with OTA DFU.
I have managed to create a .zip package (under linx, gcc compiler, Nordic SDK11,...
I want to make a program for wireless accelerometer with a microcontroller "nrf51822". I prepared the code however I face a problem with the ".h" files such as "nrf_error...
Hi All,
I'm having trouble running one of my I2C sensors connected to the nrf52 when running at a 200hz sampling rate.
Interestingly enough, the same sensor seems to...
I mean what kind of header information and stuff besides the data. I could only find this for advertising packets.
A graphic or list like this would be nice:
byte 0...
Hello,
I'm currently working on profiling an embedded application on an nRF52 using the S132 SoftDevice.
I've found that the svcall sd_softdevice_enable takes approximately...
