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 made this project to try to create RSC service on arduino

unfortunately the server starts but i'm not able to...
Hi all.
I am new in nRF BLE. I am planning to buy an nRF51822 Kit but little bit confused with choosing EK or DK. Actually my plan is after playing with the Native Kits...
I am currently designing a board using the nRF51822 chip and I would like to implement a soft power ON circuit using the low power comparator (LPCOMP).
I understand that...
Hello,
I'm using a code posted on this forum to read ADC input and fill an array with the ADC values but I always get values between 166 and 174, (even if I connect the ADC...
I'm completely out of ideas.
I've been developing a server for some time now based loosely on the ble_app_hrs sample using the 5.2.1 SD. Things have been going reasonably...
After I process some data (command) received by UART fifo module (I have installed handler for APP_UART_DATA_READY) I need to do a short atomic operation of a few instructions...
We have a project where we would like to use a balanced / dipole pcb antenna. As far as the great docs on the site stands, it's all for unbalanced / monopole antennas. Any...
Hi,
In my application I need to control a nrf51822 central device by an external MCU.
Does Nordic provide solutions to control a nrf51822 Cental device (with S120 softdevice...
Is there a register, accessible via the SWD-DP and present across ARM devices, that I can use to distinguish the nRF51822 from other microcontrollers?
Thanks,
-c
I can discover RFduino BLE devices that use the 51822 using the Master Control Panel but cannot with the nRFTemp app. The nRFTemp app scans for but does not find my RFduino...
Hi,
I have nRFStartet Kit, nRF51822DK and EK.
What is nRF2739? I am just following the setup section in nRF51SDK and it says to connect Master Emulator to PC. Is it...
Hello,
I have been attempting to get the watchdog timer working in my project without any success. I have read through all of the watch dog related threads that I could...
The S120 is a pure Central softdevice, and hence it can connect only to other Peripheral devices. Does it means that s120 cannot be used as a peripherial device?
Hello all,
I have been using nrf905 for about 5 years without problems.
now I would like to ask if is there any way to use an external PA? I am not a RF engineer and i...
Hello,
I've an issue only on IOS. My custom service is recognized as immediate alert and crash when we want to use it. It works fine on android and with Master Control...
