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

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...
Hi,
We plan to measure the sleep current of the *whole* Thingy 91 system including nRF9160, nRF52840 and sensors. Do you have a firmware (sample app or similar) that puts...
To the kind attention of Nordic support team,
I'm evaluating your standard gzp example (proprietary_rf/gzll/gzp_dynamic_pairing, sdk15.3). From what I see, the device to...
Hi,
It seems that the nRF52811 for the most part draws less current the nRF52832. For example:
nRF52811: 1.4 μA at 3 V in System ON mode, no RAM retention, wake on RTC...
Hello,
I cannot reset the nRF52 DK while running on battery power. I've tried multiple examples of the SDK which didn't work. However, when connecting the DK via USB, the...
I don't know if I'm dealing with a hardware or software problem at this point. I have a custom NRF52810 board with chip antenna and no LF clock, in SES. In SDK 16 I modified...
I'm running the esb_ptx_pca10040e on a custom board with NRF52810. The program gets stuck on....
while (NRF_CLOCK->EVENTS_HFCLKSTARTED == 0);
This appears to be similar...
Hello,
I am using nRF52840, SDK_16.0.0, SoftDevice S140 V7.0.1 and Segger for flashing the image. I am using ‘ble_app_blinky’.
1) Previously we had a custom board...
Hi,
I was testing the various cases for DFU & I was looking for any possible solutions to fix the issue.
I flashed SD + bootloader (secure) + app from SDK 15.2 on the...
Hello,
I´m trying to update the certificate of my nRF9160-DK. To do this the modem has to be in offline state. I´m running the AT Client sample like it is shown in the chapter...
I am curious if there is an inherit maximum transmit duty cycle of either M1 or the nRF9160. I am asking for this because we need these numbers for SAR test. Our product will...
Hi All,
I am working on a project with NRF52840 , we are looking for a solution to do the OTA to device by the central device , both of them are using NRF52840 as BLE module...
Hi, I need to be able to count the number of packet Tx and Rx from one board to another in order to compute a packet loss ratio for certification purpose. To achieve this...
hi all:
Use PPI+timer+adc, in the following ways:
called stop, then unable to start adc, Couldn't get into the NRF_DRV_SAADC_EVT_DONE.
Could you tell me how?
