Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
i made this project to try to create RSC service on arduino
developer.bluetooth.org/.../runningspeedandcadence.zip
unfortunately the server starts but i'm not able to...
Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
hi there!
i'm struggling with the problem about using i2c with IoT SDK.
my project is about transferring sensor data (i2c) through ipv6 over ble , so i used the IoT softdevice...
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/.../
Building and flashing...
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.
snippet from nrf_drv_config...
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...
