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...

The nRF51822 Bluetooth Smart Beacon Kit User Guide (nRF51822-BK-UG) mentions an iOS project contained in the zip file nRFBeacons_iOS.zip. Where is this file? I cannot find...
Hello all,
I'm trying to save the service context with the Device Manager on the Central side. But I don't understand the implementation on how to do this. But no information...
I'm trying to adapt the BLE_BAS_C library to perform discovery and read/write operations for a custom service. However, when I change the UUID that I register with ble_db_discovery_evt_register...
i used this function to send data to my ble device ble_nus_string_send.this function sends ASCII values. and when i pass this function hex values it converts them into ascii...
Hello,
I was using wiringPiSPI() to connect via SPI and so i was using wiringPiISR function to create an interupt handler that will do callback to the user suplied function...
I'm compiling my project successfully in Eclipse, but trying to build it from the command line (cygwin) fails near the end with this error (make, make all, make nrf51422_xxac_s110...
I want to restart the radio portion of the softdevice - all of BLE essentially - to update the connection parameters and device name mostly. Is it necessary to re-initialize...
Hello Everyone
I have designed the schematics for my prototype but i have a question for impedance matching can anyone verify my technical doubt
I had put a 2.45GHz...
We are using nrf51822 for products of our company. We use mbed + nRF51822 driver + BLE_API for the BLE peripheral devices. The softdevice is s130 ver 1.0.0.
I create an...
Can the nRF51X22 be paired with an iPhone to communicate (both ways) using regular BLE and emit a beacon signal at the same time? In fact, I'm looking to change the beacon...
So I suspect there is a very simple answer to this, but a couple days of much reading and searching haven't led me to a very clear answer.
My setup: Galaxy S3 (Android...
I'm trying to move data over the uart characteristic. I followed the guidelines here devzone.nordicsemi.com/.../
