Hello!
I set up a project using NRF24L01 and a patch antenna ceramic, the type used in GPS.
In fact, I tested several types of antennas, F, F inverted, GPS, Loop. But...
Hello,
I'm trying to create a PC application to read out some Ti Sensor Tag modules. I'm using a nRF51822 USB dongle and the Master Emulator api.
The nRF dongle sees...
I've migrated over my application code. I've noted that SDK10's new modules causes much high RAM consumption than on SDK 6.1. Everything is working however, except for the...
What are the correct parameters that I need to set in uVision to compile the experimental (signing) DFU for NRF51822_xxAC (SDK 10) (using dual bank)

Hi Nordic Community,
Could you please tell me what is the antenna reference design used in the nRF51 DK? and why a lot of BLE development boards (like Redbear BLE shield...
Hi everybody!
Im trying to implement slave spi to bluetooth bridge.
In short, when cs line goes low, i want that one handshake line automaticaly go in busy (high) state...
Hi,
I'm using the nrf52 and in my application I need to sample a sensor after applying an IR pulse; the pulse length influences the sampling thus cannot be disturbed by...
I think this is a rather common problem:
I want to expose a couple of variables from my model code (members of structs) as characteristics. Is there a simple and elegant...
Hi
Question
What is the risk/chance that future revisions (>2.0.0) of S130 will be incompatible with the setting UICR.CLENR0 = 0x1C000 ?
Background
Today we would...
Hi,
I need to wait for a period of 7.5ms whilst my I2C sensor completes a measurement, I am currently using the nrf_delay_ms function however I am looking to optimise the...
Hi
I'm trying to explore the nRF52-DK kit.
I downloaded the demo : www.nordicsemi.com/.../heart_rate_demo.zip
Dragged and dropped the hex-file to the JLINK drive thats...
Hello,
I am utilizing an accelerometer sensor and communicating with it using TWI (I2C). I have both a development kit (NRF51-DK) and the Beacon (nRF51822-Beacon). I can...

Hi,
I am using nRF51822 BLE nano with mbed IDE. I tried to set channel so that i can achieve the desired frequency for FCC testing i.e. 2402MHz,2441MHz and 2480MHz .I am...
I am looking at the ble_app_hrs_c example (with the s130 soft device on pca10028 dev board). I have set the m_scan_mode to BLE_WHITELIST_SCAN to enable whitelisting. In the...
I have implement the systick with the idea to use it for delay functions.
The systick is running normal if no BLE Events occur, but during a BLE event it seems to be stopped...
