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...

When using the nRF51822 as a Bluetooth Smart (BLE) emitter, is it possible to change the UUID, Major or Minor values by hardware (for example, by changing the digital input...
Hi, student here, so go easy if you can :)
I have successfully programmed the evaluation kit and development with the softdevice and loaded my app on.
Now I am trying...
Hello there,
I have read about SoftDevice and how it uses EMA to send and receive information over the air. However I am quit confused about what a ble stack is. Could you...
I have an issue trying to set up an example project following this guide .

Or is there any LCD you could suggest that doesn't need that much code? Simple numeric 2rows would be enough. Want to use it with the nRF51-DK to display some measured valued...
Scenario: I want to use an Arduino shield with the nRF51 DK. When attached to an Arduino, the Arduino's barrel jack is plugged into a 12V power supply. The shield takes advantage...
I am working on a ble project using the nRF51422 and IAR. I can load the code onto the board from IAR and it works as expected, but I run into errors when I run the code with...
