Hello!
I am trying to run example uart project (uart_pca10028) on PCA10028 development board. When code is loaded to the microcontroller it signalizes error - all leds...
Hello All,
I am working with a pre-programed PCB; the main components of the are a nRF51822 chip, a GPS, and a GSM. I am using a J-link to communicate to the entire board...
Hi,
I have a BLE thermometer I want to snif using nRF-Sniffer and Wireshark.
Unfortunately I'm unable to sniff the data, I only see the initial "hand-shake".
Process...
Hello,
I have the nRF51822 evaluation kit, the Keil MDK software and a custom board with the nRF51822 microcontroller on it. My question is if it is possible to use the on...
Hi I am not sure on the nRF51422 chip the iBeacon function is fully supported, is it ?
I can make the examples working on it but on the Nordic site only on the nRF51822 chip...
Hello,
we are trying to avoid using code that triggers hardware issue #39 in the nrf51822, which appears to be fixed in chips whose build code is Hx0.
We would like...
Hi,
I'm currently developing a firmware running on nRF51-dongles (PCA10028). The dongle communicates with a PC application over UART. Everything is working fine except...
