I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
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...
Hi, all.
I have been using the nRF51822 board, I am making a peripheral.
The peripheral has been equipped with a sensor to multiple GPIO.
(For example, sensor1 to P0...
Hi
I am implementing my custom service, and started from the led/button example.
I am using the LightBlue app on my iphone to connect to my device under test.
I can see...
I am trying to generate the services.h file and get an error that "Something was wrong with the advertising packet". I see at the end of the log it says "Return code: 0x2...
Hello All,
I have a basic question about empty scan response operation with the ADV_IND PDU. When I set advertising data as follows:
err_code = ble_advdata_set(&advdata...
In the download section, all other SoftDevice versions are named "(Production ready)". Just the new S120 v2.0.0 is not. Does it offer the same stability/reliability as the...
We have an nRF51822-based product that goes the SYSTEM OFF in certain situations.
We wake up with the DETECT signal from a pin which we set to sensing just before calling...
I want to have it wireless capabilities into the cable, the receiver and transmitter antenna ports with shielded wire connected directly, so there will be a wireless signal...
Hello! I want to broadcast messages between 2/3/4/5/... devices. How Can I broadcasts between devices? Each device must receive messages from others and also broadcasts to...
Hi,
I'm unable to configure the UART so, that it will generate the TXDRDY event. I have an UART that should send periodicaly 4 Byte sequences without hardware handshake...
Hi,
For my research project on novel antennas I need a demonstration prototype, and the nRF51822 Beacon Kit would be ideal for me (due to its small size and battery power...
Hi there,
I was wondering it it is possible to use MATLAB as a central device, using a third party dongle?
The MATLAB Instrumentation Contol Toolbox can be used to control...
Bluetooth v4.2 included an ability for attributes to be greater than 20 bytes of payload data long. Is there anything in the nrf51822 hardware that would prevent this from...
Hi,
Does anyone know the maximum baud rate of the nrf24l01+? I am trying to talk to it through SPI but observe that when I increase SPI speed I read incorrect values. Does...
