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...
I have bought from ebay 10 nRF24L01 and I'm trying work on a ,for more that 7 days, project sending 7bytes data. I have build (on a breadboard) the circuit described on that...
Hello everyone!
I have two sets of PIC18F45K22 and nRF24L01, one as a Tx, and another one as a Rx. I have programmed the PIC using mikroC compiler. My question is how do...
I am wnating to clarify, if i can use the Gazell protocols on the nrf51422? I can't find it in the SDK for the 51422, but it is in the sdk for the 51822.
There are some include dependencies that go like this:
app_uart.h -> app_util.h -> app_error.h -> nrf_error.h
and nrf_error.h is under Include/s110.
In order to debug...
Hi,
The err_code shows NRF_ERROR_INVALID_STATE when called sd_ble_gap_adv_start(). I want to know why it happen, and how to handle it. This happened upon the ble disconnected...
If it can work with iOS blue setting will be better
I need some reference to dev hid device in IOS
but I can just find my device ,connect ok but not work.
Is it possible with Nordic NRF51422 to perform accurate proximity ranging to make sure that a circle of 2 to 3m but not more is identified in a reliable way?
What is the...
I'm assessing whether ANT is suitable for the network deployment I have in mind, and I would appreciate to hear any thoughts you have on this.
I have a network of say 20...
Hi,
I want to change the GAP params such as connInterval, slaveLatency, and have some questions:
1.can I call sd_ble_gap_conn_param_update directly or need to send...
I used nRFgo Studio(version 1.15.1) to program S110 and application through my Jlink. But it's not worked in version 1.16.0.
It's not a good feature! :(
Is there any compatibility table for nRF51 series chips with revisions, softdevice versions and SDK versions?
I have some custom boards with a module that contains a nRF51422...
I'm trying to output a relatively high frequency PWM (300kHz). I'll need to adjust the duty cycle on the fly, without glitches and minimal time spent in IRQ handlers.
Currently...
I'm trying to build the ble_app_hrs example from Nordic's SDK on a Mac OSX 10.9.2 and have been following Nordic's nAN-29 Note v1.1 to install required tools, while looking...
Good day, I am using a USB to UART IC and it isn't working just because the nRF51822 Tx signal is inverted from this IC. There are some way to invert the UART signals?
