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...
I would like to develop my own central device to communicate with the RedBear Arduino shield. The RB device uses a from of UART communications to send data to/from Android...
I was wanting to use a nRF24L01 with a breadboard but its pin-out didn't allow it. A solution then occurred to me based on parts at hand. I wrote it up with instructions and...
Hello. Can I get a literature to the nRF51 series?
I need a full abstraction of the nRF51, like a book or other information, it's structure schematic of build-in modules...
In my ADC interrupt service routine (ADC_IRQHandler), I'd like to have a pointer available that I could use to carry some state from the main app thread to the IRQ handler...
Hi all
My nRF51822 has a incorrect LED signal, seems become a battery mode when I plug in a USB port.

I'm looking at a BLE application using the nRF51822 where we need to send data maybe once every 10 minutes, so it seems like disconnecting in between sending messages will...
Hi,
im using nRF24L01+ to constantly transmit data and all working fine, but at some point SPI fails and the only returned values I get are 0x0F - doesnt matter which register...
Hi sir
In order to simplify the flow of programming hex file to nRF51, we want to merge Softdevice hex file with application hex file. Then, generate a new hex file. Could...
I have attempted to put the radio into +4dBm mode using the command: sd_ant_channel_radio_tx_power_set(CHANNEL_0, RADIO_TX_POWER_LVL_3);
When I look at the RADIO TXPOWER...
I just got the nRF51822 DK and tried hooking up the dongle. I am using Parallels 9 on OS X 10.8.5. It only loads as a uSB Composite device with a yellow warning icon. Odd...
