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...
Hi
The NRF52832 I used seems to have accidentally turned on the read-write protection,Cannot establish a connection using JLINK now,Is there any way to turn off this read...
Hi, We are developing a robotic product using nRF52840. I would like to know if Nordic officially supports Zephyr OS and have plans for supporting features in long term?
We used sd_ble_tx_buffer_count_get() to get maximum tx message can be sent in nrf51. However, this api is removed from nrf52840.
Is it equal to the setting of NRF_SDH_BLE_GAP_EVENT_LENGTH...
I am using NRF52840 and SDK1600. Currently, my program uses 50kB RAM memory according to Segger Embedded Studio. NRF52840 has 250kB RAM memory, so there is plenty of space...
Hi,
We are building a prototype based on the asset tracker demo application. We had interfaced different sensors on different peripherals (2 on SPI and 2 on I2C). However...
I have applied the errata 171 workaround to a zephyr code base with an MX25 chip and set the speed to 96MHz - when I run the application (engineering D silicon) with a scope...
Hi
I have used ble_beacon example to configure DK board as beacon here i wanted to pass custom data inside the code and print those array code on output debug console to...
I have an embedded Linux platform which uses an nRF9160 connected via UART. The nRF9160 has been loaded with the serial LTE modem firmware, version 1.3.1.
I've been experimenting...
Hi!
I'm developing the NRF9160 target from a raspberry Pi. The problem is that I need occasionally to perform modem firmware upgrade, and I can't figure out how to do it...
Hi. I am currently using an nRF52840 DK board and SDK 17.0.2.
I have add a custom characteristic in the heart rate service sample code.
The characteristic is shown on...
Hi Nordic,
I am using your official board nrf52840 to develop my application based on the ble_app_uart_peripheral example. BLE communication and the spi interfaced sensor...
Hi, I'm working with a nordic thingy:52 and SDK thingylib on Android.
The issue I'm facing is that the real sampling frequency, compared to the one indicated by the SDK...
Hello,
I try to use the ASSET_TRACKER application with NB-IoT/ Vodafone in Netherland. Vodafone uses UDP/IP datagrams protocol. is it possible to modify the asset-tracker...
So, we are using NRF52811 with external 32MHz xtal and also exeternal RTC crystal.
Every now and then we are unable to pass tests of the programmed firmware because the...
