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...

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...

Hello,
I am currently sampling SAADC every 1ms using PPI. Samples are collected in predefined buffer, and then send over BLE with ble_nus_data_send() function.
I would...
If I use sd_app_evt_wait() or nrf_pwr_mgmt_run, I lose TWI. In other words, in order to use TWI, I need re-initialize it. If I use:
__SEV(); __WFE(); __WFE(); It works but...
Hi,
The NRF52DK we use is interfaced to a capacitive touch keypad and an RGB LED. The board works fine when supplied by the USB but when we try supplying through the external...
I am trying to update the firmware via OTA , while uploading the firmware I am getting "upload failed" message on the nrf connect application.
I am using nrf51422 board...
We currently are investigating a move from nRF52832 to nRF52840. The reason for this is that we need a more powerfull radio - more range (even if that means lower throughput...
My environment: DK 10040, nRF52832, SD 6.1.1, SDK 15.2, SES 3.52
When does the SAADC use power? And when does it stop using power?
I searched the 52832 specification and...
I am trying to run the example from this page: www.nordicsemi.com/.../Getting-started-with-the-nRF52-Development-Kit
I have PCA100040 somehow after running blinky and others...
I am trying to get a driver from a third party binary to work. Their library was compiled without using the HW FPU. I had to compile my code to use the softfp. I also added...
I posted on the Adafruit forum but there doesn't seem to be much support there. Since the module is based on nrF I'm hoping this community can help out.
For the most part...
hi,

Hi!
I need to know before connect on the central side (from advertise data), that this piripherial device has already bonded.
Is it possible...
I'm having some trouble setting up 2 transports (BLE + USB CDC ACM) with the secure_bootloader example. The changes I made were:
- Increased flash size for code space in...
Hi,
It's my first design with nRF52840 (I have make multiple design with nRF51 et nRF52 without problem).
I use SDK15.2 and BLE_peripheral_blinky example without modification...
I'm using nrfjprog to develop a production functional tester for an nRF52840 based system. Everything was going well in testing, but when I moved the hex file to be loaded...
Hello
I have a problem with ADC measure and accuracy.
I want to read a voltage (U_BAT+) between 2.5 – 4.5V with an accuracy of < +/- 50mV
I have two scenarios. ...
