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...
SDK: nRF5 SDK for Thread and Zigbee 1.0.0
I have code for the SAADC based on the Low Power SAADC example here .
I have modified it to sample 4 inputs, and changed the...
Hi,
I would like to check battery level using the SAADC of the nrf52840.
Assuming the voltage is less than 3.6V, do I need to have a resistor between the battery and the...
HI,
I am new to IoS development with NRF.
I am having NRF52840 DK, IoS device. I want to implement USB HID device application (similar to pulse/Gluco meter ) on IOS. I...
Hi,
I am not able to compile the SDK example by using SES for ARM V3.52.
I got one error which shown below:
It pointed to the link ldr r0, =%4
Thanks

Hi,
I am using fatfs of nRF5_SDK_15.0.0_a53641a.
I am writing a program with keil.
I am currently doing SPI communication with BLENanov2(nRF52832) and SD card with...
Hi,
I am implementing the UART on NRF52840. TX works but the RX doesnot. While debugging, I noticed that STARTRX task register is not getting set due to which the RXDRDY...
Hi Sir
We'd want to do RX testing with DTM mode, however, the dtm example code looks can't report receive data or total packets counts,
So that, we don't know how to determine...
Hello,
I'm using the nrf15822 chip and am using the ble_app_uart example from nrf5_sdk_12.2.0.
I know softdevice will automatically generate random numbers through RNG...
I've been told due to PAN 58 it is not possible to use EASY DMA with nrf52832 without switching to the deprecated SPI driver. Is there a workaround that allows the use of...
Hello,
We are going start custom PCB design by using nRF52840 chip and SDK 15.0, but confused for use 3rd party nRF52840 modules or design complete custom PCB using componenets...
Hi,
Despite knowing a fair bit of the theory of wireless comms (mainly PHY and MAC), I'm brand new to actual hardware configuration/protocol development, so please be gentle...
As a master device with a whitelist there is a limitation on how many slave devices can be connected. If i am correct, other than whitelist there is no restriction to the...
Hi,
How do I receive data from host (computer) on my BLE device(Nordic board)? I want to use a simple open source HID API to send data to Nordic board and glow an led or...
Hello, we have finished all prototyping with BLE modile from Taiyu Tuden, this module: https://www.yuden.co.jp/wireless_module/document/datareport2/en/TY_BLE_EYSGJNZ_DataReport_V1_9_20180530E...
