I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
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...
Hi All.
Currently we are using buttonless-dfu service to upgrade firmware via ble on an nrf peripheral-device (via nrf-connect app on mobile central-device). Next, in order...
I am trying to implement the central side code for the usbd_ble_uart example. My current target is the nRF52840 Development Kit but the final target is the nRF52840-Dongle...
Hello!
I am developing a solution that has a gateway and about 10 devices.
The devices has some sensors and their are connected in gateway. Actually I catch the sensor...
Hi:
I am having a problem with the fstorage and ble_stack_init. When fstorage is used before the ble_stack_init it works fine. If used after ble_stack_init, the fstorage...
Hi,
We are developing a BLE peripheral that support DFU and accompanying Andriod & iOS apps.
When using the following tools, (buttonless) DFU concludes successfully...
Dear Nordic,
For my application I am now using a NOR memory with my nRF52840.
This memory needs the FAT file system as my device implements USB MSC and uses regular...
I am currently trying to modify a Zigbee-only application (with no SoftDevice, originally based on the light bulb example) to be placed on top of the SoftDevice. The app will...
dear
in the case :our product is produced in factory, we want to upgrade new app via phone,
but the crc of new app is not equal with the origin one which store in the...
Dear Colleagues,
I am not sure whether TEMP anomaly 31 is applicable to nRF52832-QFAA-0B (NRF_FICR->INFO.VARIANT == 0x41414230)
nrf_temp.h @ 65 says:
static __INLINE...
A happy new year everyone,
I should develop a mesh sensor network for Raytheon Anschütz GmbH in Germany but I am an absolute beginner on Zigbee and therefore struggle a...
I have a BLE project that I wish to add Zigbee to (non-concurrent, if that matters). The project is built on FreeRTOS with several threads, using SDK 5.2.0 and S140 6.1.1...
Hi,
I am using nRF52840-DK evaluation for testing a Mesh configuration. I was able to successfully establish a mesh connection with a onoff-sample from zephyr and was able...
I am working on the project with radio transmitter(NRF24L01+) and receiver(NRF52840). I need to receive data at the rate of 250kbs. I tried to receive but it fails always...
Hello,
I want to interface a microcontroller with the nRF52832 chip in one of our designs. The microcontroller will be running on FreeRTOS.
I would like to know a few...
Hi,
We are currently in a testing phase of our software where we use an nRF52832 for extended advertising and an nRF52840 for scanning that has a scan interval and scan...
