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,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...

Hi,
So I'm using a BT 4.0 dongle (Laird BT820) to set up a LE notification loop with the nrf8001 (RedBearLab shield on Arduino) using gatttool on Ubuntu 12.04. This works...
I've used the nRF8001 on several projects with good success, so I'm generally familiar with the chip's operation. But I'm seeing an issue on a new (custom) board that I'm...
We are currently researching which BLE chip vendor to use so this question is directed at Nordic personnel familiar with the S110 stack's capabilities.
In a situation where...
I would like to use the nRF51822 evaluation kit as an observer to detect beacons and take action based up the RSSI value. I can't seem to find any source code for S120 or...
I got the Dynastream N5 kit and have successfully used it with limited ANT work and was trying to get BLE working but can't get a driver for the USB dongle. On the 51422 product...
Hi,
Repro, using the Nordic hid-profile + iOS 7.1.1:
Pair the nrf51822 based hid device via the iOS bluetooth menu.
Turn off nrf-device.
Boot up the nrf-device...
I want use pstorage write and erase flash,as shown below:
