Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,

We have an NRF51822 running S120 at 32MHz.
Our system has two removable batteries. If a battery is removed we need to switch to the other battery as fast as possible. We...
For TWI, SPI and UART is there a significant power savings from powering down the unit when not in use vs just disabling it?
Disabling the unit seems reasonable, but powering...
Hi!
I was trying to use nRFLoader to update firmware using example DFU Bootloader but app hangs on "Discovering" (after selecting device to update). What can be the reason...
Currently I can upload new application firmware smoothly (I use the dual bank setup). However, I have to use packets of size 20, so this takes a long time.
Is there actually...
hai ,
i am using the NRF51822 development kit. The NRF51 dongle i have used as a sniffer and a master control panel. Is it possible to load and run a s130 softdevice and...
Hi, I'm trying to estimate the nRF51422 current when running ANT. Does the softdevice use the RTC (LF oscillator) when in wait mode to save energy? Thanks
The Segger programing interface works. The virtual com port appears on my PC (COM5). The problem is that there is no board listed in the Motherboards section of the Device...
Hello,
currently I try to implement a GATT server on a nrf51422 with the s310 Softdevice. For testing I use the LightBlue IOS client on an ipad. I can see my GATT server...
I am creating an Apps which will give me a list of the running Apps in the background and foreground.
Hence Using XCode, I want to programmatically detect

I have a Arduino board and I want access to Ant Stack by UART. I flashed S210 in my nrf51422.
I try connect the Arduino RX/TX with TX/RX (P0.12 / P0.13), but none. Also...
Hi Nordic,
I'm wondering if I can use IAR Workbench to download SDK for nRF51DK rather than Keil. I want to develop a beacon that uses Bluetooth Smart. Can I do that in...
