Hi all,
it's possible to use a DCC pin to power an external element (like a led, for example)?
If, yes what is the maximum voltage that we can have? It's V battery or...
Hello
I just bought a NRF51422 (PCA10031 v1.1.0) dongle. It worked for sniffing, but after I upgraded the bootloader as indicated in the MBED post ( developer.mbed.org...
I'm having a strange problem, where sd_app_evt_wait() won't make the CPU sleep, after I've started a app_timer (consuming >2mA). Its working perfectly before I've started...

Hi, this is my first question here. I am using softdevice S120 v2.1 for connecting and discovering a custom service with 9 custom characteristics. I was trying to read all...
Master Control Panel occasionally works for me, but at other times it will never launch. I click on the app, something seems to happen but the window never appears. I tried...
Hi,
I'm looking for an easy way to send raw data measured by NRF51822 (as single bytes) to a host computer, without using Nordic dongle.
The example project ble_app_uart...
Hello!
I have a problem with getting a value (uint8_t) from a characteristics.
I am using 2 nrf51422 boards, where one is a central and the other is a peripheral. I...
