Developing on the nrf51822
Have working code for the nRF52840 Dongle using the pc-ble-driver therefore all Bluetooth work is done using sd_* calls. The PC provides easy...
Hi ,
I would like to know if a matching network is needed if I am only using a single external flex antenna for both LTE and GPS using a RF switch between them and a uFL...
I am a student interested in Nordic.
My coding skills are very poor.
So I want to get help.
I want to use the vl53l1x sensor in nrf52. (My ultimate goal is to measure...
I have a working project where pin 16 is configured as a low-level interrupt source.
it is working well with SDK 15.3
after porting to SDK 17.0.2, it is not triggering...
Hello Nordic Support Engineers and fellow developers ...
Just a note to thank everyone for help via this forum. I started very inexperienced with Nordic SDK a year ago and...
Hi all! May I use another quartz instead of 16 MHz? Will the output frequency equal to 2.4GHz/16, if I will be use the 1 MHz quartz? Or IC will not work? Is it possible to...
I need to evaluate the real consumption of current for BLE events on RF81822. The HFCLK is 16MHz and the 32kHz clock is external.

Hi, I am using S120 1.0.0 and SDK 6.0.0. Learning the sample project 'ble_app_multilink_central'.
I already got a peripheral device with NUS service. The central device...
I am new to this great platform and am struggling with getting my PIR sensor connected to my DK. I wonder if some of you experts could give me some pointers on how to go about...
Hello, I build a BLE 6LoWPAN environment on my raspberry pi with Kernel 3.18.3 and connect a BLE Dongle. The BLE Node is Arch BLE ( www.seeedstudio.com/.../Arch-BLE-p-1998...
Hi, I have two different types of nRF24L01+ modules, both behave differently.
The "troublesome" module always has TX_DS asserted after a transmit, which is the same behavior...
Hi,
I am using the SPI Master 1 to control an EEPROM. I used the spi_example project to help get the code working. It all works fine if the code that initiates the SPI...
We have designed a differential antenna for the nRF51822 CEAA chip.
Each of the RF output connects through a matching circuit to each one of the two 50-ohm to ground end...
How to setup MQTT for CloudMQTT? I have working raspberry PI I can ping and connect to device when follow the user guide. Now I like to try MQTT example but don´t know how...
Is there a list of every interrupt these functions effect. Specifically I am worried about
static void ble_evt_dispatch(ble_evt_t * p_ble_evt)
My assumption is that...
Is there any S110 demo with good communication between periphera and APP in phone side in SDK 6.0? It means that data channle works well from 51822 to APP and APP to 51822...

The nRF51 series reference manual v3.0 documents 3 Real Time Counters: RTC0, RTC1 and RTC2 (pp 17 and 109). However, RTC2 does not appear in the SDK documentation (e.g. no...
when I download program(pin_change_int_example) in nrf51822, Immediate Interrupt is occured
And when I push the button, Interrupt is stop...
What is problem?

Hello,
I am designing a board based on the SoC nRF51822. Since this is a homemade project I do not have lab equipment so I can not measure antenna impedance and therefore...
