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...
Hi, Nordic
I want to change usb in/out packet size after hal_usb_init().
as I know, it should make one report descriptor and update.
But I can not see similar demo...
My latest assignment is adding NFC functionality to the device (the very same device that I had trouble with DFU on). Adding the functionality was easy enough but I'm having...
I have seen this topic:
devzone.nordicsemi.com/.../
and a few others, in an attempt to visualize the RAM usage of my project. I currently use GNU ARM Embedded (gcc)...
Please clarify the radio state diagram for the nRF52: it shows a black dot between TXIDLE and RXIDLE states, having arrows from TXIDLE or RXIDLE leading apparently back to...
Hi guys!
I wanted to ask that can we use an external flash(connected via SPI/I2C interface to the mcu) instead of internal flash for storing downloaded image(s)?...
Background: We use NRF52 chip along with SDK 12.1.0. Since we have a few components of firmware (i.e. secure DFU settings, secure DFU , application, Softdevice) that go into...
The aim is to use the nRF51822 chip beside the application processor and to run the soft device S130 in it but as I saw, the newest SDK v12 supports only S132 Connectivity...
I am trying to update my S132v2.0.1 devices over the air to S132v3.0.0 and am getting no bootup, even after swapping dfu_dual_bank.c from the answer below.

I am studying this tutorial: nRF52 Online Power Profiler . I know this tutorial basically related to the ble_app_pwr_profiling example in the SDK: Power Profiling Application...
Hi, Nordic
I know pipe0 and pipe1 are be enabled on nRF24LU1 nRFgo SDK example for default PRX.
Now I only to enable pipe0, disable pipe1.
First, I use this...
Hi, Nordic engineer
nRF52832 as ESB PTX, nRF24LU1 as ESB PRX
same channel, crc, and match address and pipes, but from nRF52832 uart log, ESB TX fail event always show...
I'm using an nRF52 (SDK11.0.0, s132) and am able to generate a hex and axf via Keil/uVision. It uploads and works just fine using a Segger J-Link. I want to try some lower...
Hi, I'm a newbie to Nordic and need to use multiple nRF24LE1s to get ADC values and transmit them to a single nRF24L01 connected to an Arduino. I need sample Keil compiler...
Hello everyone~
Although one TWIM interface of the nRF52832 can "interconnect up to 127 individually addressable devices", I still think that use different interface will...
Hello everybody.
I'm trying to modify the original firmware that comes with the nRF51822 to make it sweep all of the permitted levels of transmission power.
I was able...
