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,
My application is to scan BLE advertising packet.
My application works when the scan_phys is set to BLE_GAP_PHY_1MBPS.
params.active = true; params.interval = NRF_BLE_SCAN_SCAN_INTERVAL;...
I'm specifically interested in the predefined SPIMn - SCK, MOSI, MISO, SO pins for this device, so that I can marry this information into my CPU Schematic Page. Whilst the...
Hello,
In our application, we have an external watchdog IC. We need to test the timing of that chip during our board power-on self-test.
We currently achieve this by setting...
Hello!
Recently we have noticed that some of our devices has been reporting strange fulgurations on their reported battery level. This is a graph over 24 hours:
When...
Hi I am the evaluation board of nRF52832 (TAIYO YUDEN Evaluation Board) EBSHSNZWZ) is used. I want to use P0.09 and P0.10 of nRF52832 as PIN of GPIO(TWI). It was set according...
Hi,
I'm developing a serialization system with nRF52832 and an application chip. My product is a power-sensitive.
The code of ble_connectivity in nRF5 SDK 17 calls nrf_drv_clock_init...
I've run into an issue with FOTA updates. The issue can be described by the following sequence of events:
A device is completely erased and programmed with a binary image...
Hi,
I am working on programming a bootloader on a NRF52840 DK using a different NRF52840 DK. Currently I have them connected via the debugger and have been successful in...
I am trying to port my build from Eclipse (based on the GCC tool chain) to a KEIL uVision build system.
I am using KEIL ARM Compiler version 6.15. Most of the files compile...
I see many similar questions to this, but I want to double check my understanding.
We have the nRF52840 connected to D-/D+ on a USB Type-C connector. We have a standalone...
Hi all!
I'm using an nRF52833, SDK 17.0.2, s140 softdevice 7.2.0. My design uses a Skyworks SKY66112 amplifier.
I have the pa_lna_assist function that I found here on...
I am running the example:
