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 having an issue with timers. They work fine for shorter timeout values (<8hours) but after trying with a timeout value of 24 hours, my timers expired immediately...
Trying to implement the BLE peripheral advertising code, but sd_ble_gap_adv_set_configure() in ble_advertising_init() returns error NRF_ERROR_INVALID_LENGTH. Any help will...
Dear experts,
My app needs to monitor an incoming DRDY signal changes at 200Hz to 16000Hz. I am considering to use NRFX_GPIOTE driver to detect the DRDY event. It seems...
Hi Nordic,
I was checking the ble_app_uart_coexist example application and it says it is a combination of both UART & Mesh. So would this support provisioning via mobile...
Hi, team. ********** environment : SDK : Mesh v3.2 (w/ SDK v15.3.0) SoC : nRF52840 IDE : SES ********** I am challenging to handle each event, such as Mesh receive interrupt...
Hi all,
Radio notification inactive state interrupt is coming but I was not able to do any action by comparing it.
I am thinking, if radio_evt is false then it is radio...
Hi,
I need trigger repeated SPIM via PPI for a batch of samples until the given RAM buffer is full. Then I need start another round of batch SPIM with another buffer.

Hi,
I am trying nrf52832 with pca10040 board. My app uses s112 soft device and also SPIM0 to collect data from a slave device. No event handler has been used when initializing...
I want to know how to control BLE connection of nRF52832. I am using softdevice S132. I have a device that works centrally and a device that runs peripherals. When the peripheral...

I am trying to interface I2C EEPROM (AT24C512) with nrf52840 and I am directly writing to and reading from the registers mentioned in the datasheet. I am seeing the i2c waveforms...
Hello -
We are also bumping into the problem described here , where it is not possible to initialize LESC when BLE is initialized from a FreeRTOS task. The nrf_stack_info_overflowed...
