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, I'm using nrf51 without ble.
I want to update flash but not want to delete PAGE every time.
NRF_NVMC->ERASEPAGE = (uint32_t) page_address;
How can i do?
We use IOS DFU toolbox to upgrade firmware with BLE device. we can upgrade successfully with Android, but always failed with IOS.
wrong code is: DFUErrorReadingVersionFailed...
Hi, it's probably a very dumb question, but i don't seem to find any details about it. In nrf52 SDK documentation, in Error Module section it says
The behavior of the...
Hi friends...!
I want to put dynamically changing MPU data into the advertising packet. I am putting my accelerometer data into manufacturer specific data field of ble_advdata_t...
How robust is the output PA of the nrf905?
Assume the ouput matching network and 50Ohm connector is used as in the 868Mhz application note.
If the antenna is removed...
Hi,
I'm trying to find a way to speedup the upload procedure of an application, via BLE on a Arduino Primo with the DFU service.
Here you can find my code:

Hi,
I am using ble_app_uart sample code for testing. In that I want to store the incoming data into to three buffers and simultaneously sending this over BLE. i.e., consider...
hi i m using nrf52832 for detection acceleration , angular speed and detection of magetic field with GY-87 ( MPU 6050 and Hmc5883). in fact i wrote a program that read only...
Hi,
I am using s130v2 and running the example code from: nRF5_SDK_12.3.0_d7731ad\examples\ble_peripheral\ble_app_hrs\pca10028\s130\arm4
This is the only modification I...
Hi,
I know this is a Bluetooth 5 spec question, but wanted to know the practical figures for current consumption when nrf52840 is used as both central and peripheral...
Hi,
We are expecting many of our devices to be in close proximity. How can we be certain that when a user initiates a buttonless DFU, that they are uploading to the correct...
Hi,
I thought central is the one which fills up its look up table with 16 bit IDs to keep track of the peripherals. If multiple devices can act as central at the same time...
I am trying to re-base my SDK package, and when I started off with the ble_app_template project for the pca10040 s132, I copied my main file on top, everything compiles just...
