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...

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...
I'm looking for a low energy communication method for a wireless PIR motion sensing device. The system will be battery powered so RX current draw is particularly important...
We are revising a design using the NRF9E5, we are experiencing problems with the third harmonic when configured for 915MHz band, the higher we go up the band the worse the...
I am looking to build a custom board using nrf52840 and want both UART and flashing capabilty on the custom board. I have a NRF52840dk that I will use to program the custom...
I want to increase the pull-up resistor value to educe the current consumption.
but, I am afraid that the GPIO input will not be recognized as High.
I want to know the...
Hi,
I can't find this information anywhere in the AT command manual or datasheet. What is the accuracy for " AT%XTEMP?" and "AT%XRFTEST=10,1,0"?
Kind regards,

Hello,
I'm trying to generate project to realise new user-cases with wireless mesh networks.
I did a demo with the Thingy52 at flower greenhouses
They are very interested...
HI! I've done the basic Blinky and UART examples, and now have to move on to programming something on my own. ( I have to send EEG signals from one BLE board to another/notebook...
hai ,
i tried nrf52840 ota over BLE from third party (ESP32).
As per the DFU protocol implemented logics and upto init packet (.dat file) getting expected response from...
Hi, I'm looking to use P15 (Shield Debug out connector) on nRF9160-DK. Description here https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nrf91_dk%2FUG%2Fnrf91_DK%2Fhw_debug_out...
Hi I used the light ctl/lc example project and connected to it with my iphone app which uses nordic sdk. I made a slider which sends messages quite often to the mesh device...
We are presently using Raspberry Pi 3 Model B to observe BLE packets coming from sensors that have NRF52.
We are also able to do DFU OTA using the Nordic NRF52840 USB dongle...
Hi,
I am working on a design of very low power sensor, based on nRF52833. Most of the time my device spends advertising only, with sensor data transmitted within advertising...
