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,
I have a battery powered device which goes to system off mode when it is not used. I want to do some stuff when the battery is inserted the very first time after production...
My application uses the Softdevice, app_timer and app_pwm.
So all timers are in use, but I have to measure two more pwm signals on two input pins.
(Those come from HC-SR04...
Hi,
I'm resetting the chip externally using the reset pin to not be in debug mode. I'm running the system off example here modified to not use buttons.
I have the J...
Hi,
I am looking for some assistance to choose the best way using the nrf52832 processor in a correct way.
The main task is to generate a 1KHz PWM Signal with changeable...
Hello,
I am using nrf51822 ceaa package.
What would happen if dec1 pin is not connected to a capacitor?
According to the datasheet, it is for power decoupling and...
I'm developing py script for automation testing of nRF devices.
My script is based Nordic's scripts Master Control Panel\3.7.1.8567\lib\dfu...
So, during testing my script...
Hello,
I have some devices based on NRF51822 using ESB lib and developed with Nrf51 SDK v10 (no softdevice). Since Nrf5 SDK v11 is released, the new device will be developed...
Hi,
I am curious about how the connection is keep while using the 32.768K in BLE link layer in power saving mode.
I know that the connection interval is based on multiple...
Hi,
I have two BLE centrals and one BLE peripheral. Both centrals are in range of the peripheral and both want to connect to the peripheral at exactly same time. What central...
Hello ,
We are working to an OEM Security System project that is using BLE.
The system contains at least 2 modules that communicate using the BLE technology.
One of...
I am trying to run the example ble_app_hrs on the nRF51 dk PCA10028. I target and build the file, and I believe it makes it onto the device, as the old program on the device...
Hi,
when i program my eval kit using nRFgo studio, the chip dosen't work unless i do a hard reset OR put off supply and put on again.
Any idea ? My program, is dfu bootloader...
Hello Nordic Team,
I am sorry to say this, our development team found a major glitch in micro-esb communication protocol. we are in stage of pre-production of medical sensors...
Hi
We are thinking of using NRF51 for BLE and CPU capabilities. But we also need a Wifi add-on to connect to cloud.
What is the right chipset for this? Which ones are...
I have a demo(s110) set up with some custom services, and in them custom characteristics. The services each relate to a specific sensor element on my device, so have a mostly...
