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

Hi,
I've been working on a low power application where every 10's of uA is important. My application requires SPI as...
Can you provide documentation of the energy costs for creating/verifying ed25519 and NIST P-256 signatures with the CryptoCell CC310 peripheral found on the nRF52840 device...
I am trying to set pins when I press a button, and clear is as soon as I stop pressing the button, however the board turns on all leds at once and does not respond to input...

Hello,
I am looking into migrating DFU and Bootloader over BLE from SDK v15.0 to SDK v15.3. I have a few questions about the code changes which I was hoping I could get...
I was reading about Mesh DFU and noticed that when it happens, the receiving node will rebroadcast it to all devices within radio range. It seems like devices will pick up...
Hello all,
I am trying to adjust the current consumption of my device based on nrf51822 s130.
A have read the https://developer.apple.com/hardwaredrivers/BluetoothDesignGuidelines...
I wrote some user data to 3rd party nrf52840 boards flash using the command "nrfjprog --memwr 0x1001084 --val 0x33333333" , when I ran the program the data values was not...
Hello,
I want to test the mesh provisioning demo with the codes provided on the GitHub:

We are using an NRF52840. After initializing a UART that uses P0.06-TX and P0.07-RX the following function calls fail: sd_ble_gap_device_name_set() and nrf_sdh_enable_rquest...
I am playing with the TIMER peripheral and I am seeing that I must call the function "nrf_timer_event_clear" in order to get the TIMER interrupt to stop firing once a COMPARE_EVENT...
As shown in subject, I tried to register many BLE services, DIS, BAS, HTS, and Custom Service. Then nRF52832(and nrf52840 preview) has stopped by an error of NRF_ERROR_NO_MEM...
I am working in nrf52840 sleep mode and it is working perfectly in system_off() mode, but while trying to wakeup from sleep using timer the device is not waking up because...
