I'm trying to use the nrf8001 (and arduino) to send MIDI (musical note data) to Mac OSX. According to the Apple developer site the midi profile requires that the characteristic...
Hi
I use an avr attiny441 with the nRF24AP2. Communication is over SPI byte flow. After start up, I get the start-up-message from nRF24AP2. That's fine. Afterwards, when...
Hi
the PWM frequency should reach 8MHz( duty cycle is 0.5 )when use timer0(16M) without SD.but i revised timer demo code from peripheral and only get 50KHz.i don't know...
Hi everyone,
I've found a few posts and a lot of info but I'd like to know if there is an existing example that merges a few of the examples found here ( github.com/.....

Hello.
I use SDK 8.0.0 and PCA10028 board. I try connect board to the Windows 8.1 PC ( i have Tablet PC and Desktop PC with BLE dongle). For connect board to Windows i...
I think I understand what these two flags do, the SYS one returns the system attributes, which I assume means data representing the CCCD for the service changed characteristic...
Hello,
Is there any compatible arduino lcd with existing library for the nRF51 Chipset?
So I can just plug it on the nRF51-DK, include the library and "lcd_wirte("text...
Dear Developers!
I'm a newbie in nrf51822
My Project needs to change between central and peripheral role. How can I apply OTA DFU with S130 soft device ?. In nrf51822 DFU...
Hi,
I used PPI module and Timer2 to generate a 4Mhz pwm. But I founld when using softdevice(s110 v7.0), the pwm will be broke a while by BLE advertising or connecting event...
