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...
I have a custom made board that has an EFM32WG360F256 communicating to an nRF8001, verified that the ACI protocol works with repeated echos, however when I run the efm_ble_my_project_template...
Hi,
I have 3 nRF51 DK pca10028 v1.1.0
I compiled and run power profiling example and after that I cannot flash or connect to the devices (tested in all three of them)...
Hi Guys,
Thanks for your precious time and insight. Let me try to explain what we did,
We have developed a custom board
After assembling the board, we do a bare board...

What is the official status of the Softdevice Serialization for S130 in SDK 9? I could see an older answer on how that was removed in SDK 8 but since almost half year has...
I'm considering purchasing a nrf51 sniffer USB dongle. I believe I can use this to sniff beacon packets and with wireshark view the packet internals, data, channel number...
Hi
I tried to flash the softdevice with nrfprog, but it does not work. Even with nRFgoStudio it does not work.But with IAR I can program an example of the SDK (without...
Hello, all
I have a problem with ble data exchanging.
I have programmed an application which controls servo motors through phone application.
At the connection, ble...
Hi,
I am trying to use the SAADC to periodically sample an input from AIN0 and send the resultant data over a BLE link to a phone. Going through the forums I saw that the...
Hi,
I am trying to debug the blinky example project on the nRF52 development kit.
I have followed the following tutorial: devzone.nordicsemi.com/.../

I'm in the process of designing a circuit that requires Bluetooth. So instead of having a separate chip for Bluetooth and processing, I decided to use a Nordic Semiconductor...
Classic C documentation issue. Are the values that are passed by pointer (p_peer_address and p_whitelist) to sd_ble_gap_adv_start() copied into that function, or do they need...
I'm trying to read the 32-bit value of TIMER1, but it seems the value I read is always 16-bit value. When I debug the value is never above 0xFFFF.

The peripheral is actually a dual-mode device, with BLE being a peripheral device.
I can connect to this device and discover the GATT services with the nRF Connect iPhone...
What is the minimum and max value that the NRF_RADIO->TXPOWER register can get set to? The datasheet it takes a signed 8 bit for the setting, but what happens if you set it...
Hello,
I am trying to read data from nRF51422 ADC using SDK51 PCA10028 board downloaded with S130. I tried one of existing ADC with Softdevice examples, it seems to work...
I have meander antenna design on my board with matching network(similar to PCA10031).
Since I don't have access to VNA or Spectrum Analyzer for tuning antenna, I am tuning...
I'm building some code off of the twi_master_using_app_twi example which is available in the SDK (v11.0.0).
The two peripherals I'm working on are an accelerometer (LIS3DH...
I've just upgraded to Windows 10, and I've found that the PC freezes completely (i.e. no mouse movement, no keyboard response) when I unplug an nRF52 DK board. When I plug...
Hi,
In my application, I need 3 PWM to drive LED. Each PWM will have the same frequency but not the same duty cycle.
Is that possible to do that?
I know that Timer0 is...
