Is there a way to modify the code in the ios nrf beacon app to identify nordic beacons?
I am aware that the manufacturing id must be set to 0x004C in order to be identified...
Hello,
Is it possible to create a GATT service with a 128 bit UUID, where each characteristic has a unique 128 bit UUID of it's own?
Looking at the examples, it seems...

Hi all ,i wanted to know how to start programming with nRF 51822. i have tried many times to load or download program but i failed .actually im new in nordic programming even...
Nordic offers many features in their libraries that rely on callbacks, but the use of void *context pointers to allow proper object oriented programming is sparse. For example...
Hi,
I'm currently working on an application that collects audio data and sends it to a central device via BLE. Since audio compression has great potential to reduce power...
Hello Sir,
We developed one application in that we use WiFi and interface this to nRf52832 chip using UART. The WiFi Ch_PD(Chip enable Power down = GND for low power consumption...
Hello everyone,
I would like to know how the (G)FSK modulation on nRF52832 is realized. Is my assumption correct, that a Fractional-N PLL in combination with Delta-sigma...
I have the precompiled code running on two seperate nRF52832DK PCA10040 1.2.1 boards. The example appears to do exactly what it said it would do. However I cannot detect any...
