I am interested in the S130 ability to hold 3 central -> peripheral links over BLE, and am looking for some evidence that this has been accomplished with extremely low-power...
I'm trying to implement channel scanning in our nrf24lu1p based USB dongle.
I'm following the specs and basically loop though each channel ;

Hi,
I am using the NRF8001 in UART mode and attempting to bond with my android device (Lollipop 5.0 Nexus 6).
i am using the nordic arduino sdk which is found here:...
Hi, I'm using the nRF8001 in an application that requires security so bonds to the remote client/central. My device supports firmware upgrades that may involve new nRF8001...
Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

We would like to be able to calibrate the rRF9E5 ADC
Our proposal is to permanently fit voltage dividers, each using two precision resistors, on two of the ADC Ports and...
in prj.conf, i add below:
CONFIG_BT_USER_DATA_LEN_UPDATE=y CONFIG_BT_CTLR_TX_BUFFER_SIZE=251 CONFIG_BT_CTLR_DATA_LENGTH_MAX=251
in att_internal.h , change # define BT_ATT_DEFAULT_LE_MTU...
Hi!
I wonder how can I measure the delays, latency, errors and connection speeds. I'm using nrf samples for bluetooth peripheral_uart connect it with nrf connect app. I...
I have a SPI Master and a SPI Slave. The Master will randomly pull data over SPI from the Slave. The slave will randomly generate events that result in data to be sent to...
I am using SDK version 17.0.2. The example code uses SPI.
The following changes have been made to the pin settings.
Questions
1. Pin behavior is strange.

Hello, Support team.
Our boards do SPI communication to read sensor data.
Basically It works well. I checked that It operates more than 5 hours.
But only one board...
Hi,
I have the following initialization for advertising:
The name consists of an acronym od three letters and a underscore e,g, XXX_ and a six digit ID. Like XXX_12E124...
Hi,
Is it possible to add four pairs of resistors between the debug signal lines and the connector as shown in the figure below.
Would such a connection not impair the...
The Google Fast Pair Service has recently been included in a number of Bluetooth peripherals (Headphones, fitness trackers, etc.) and has been getting rave reviews.
Has...
I am able to download simple blinky program on my custom board. It is working fine. Custom board is interfaced with nRF52-DK through P19. I am using embedded studio as IDE...
Hi, on nRF5340 I want to capture accurate timing of external events. I need a kind of real-time capture module to read the time period of a pulse train generated by a rotating...
Have a few questions about ble_app_uart example.
From the way I see it, it sets uart_event_handle as the callback, and every time there's an "event" that takes place...
Hello All,
Method 1: I am writing a test application to read the ADC data at a specific intervals(10 samples for every 5ms interval for every 50sec). I am using blocking...
Hi,
We are implementing a synchronous light flashing of multiple devices, so:
1) Can we get a millisecond level (< 10ms) time synchronization by parsing the Link Layer...
Hi, all
I added a scanning module to the example 'ble_app_uart.c', so each one works well.
What I want to do is advertising and connect at the same time while connected...
What is the best practise for multichannel SAADC conversion in ultra low power devices? For example I have to measured 4 channel in interval 250ms. Below what I try:
