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...
i made this project to try to create RSC service on arduino

unfortunately the server starts but i'm not able to...
I'm using the mbed platform and have been battling hard faults as I try to find the best way to write with high frequency to SPI to update a series of LEDs while still allowing...
I'm migrating an old (but working) app from the S110 5.2.1 (SDK 4.X) to the latest SDK9/S110 8.0. I've read the migration doc, and I'm following the examples carefully (specifically...
Hi,
I downloaded latest version of SDK and all examples resented there are for nrf51422.
Can I use those examples for nrf51822?
I'm using ukeil and I can only select nrf51422...
Our chip seems to be running at ~500uA and I'm trying to narrow it down.
I'm doing periodic battery level checks on a timer using the ADC HAL. So at init I call nrf_adc_configure...
I use s110 send notification to s120 in 1 - 1with 7.5ms connect interval,but the data maximum data throughput is only 21.3 /2 kbps.how can i do to raise the throughput???...
i use s110 send notification to s120,and set connect interval with 7.5ms,but in actually the connect interval is 15ms!!I see s120 softdevice specification,s120 as client which...
Hi,here i met an issue that when i set address type in public mode by funtion sd_ble_gap_address_set(),and then the advdata packet data was all zereo.This project was created...
Dear ladies and gentlemen,
There is not much information about the RESET pin in the datasheet. I guess, it doesn't have an internal pull-down resistor, but when I look at...
Hi,
I have a problem configuring readback protection using boot.
It seams that the BOOTLOADER stops when trying to read some information from the softdevice if readback...
HI:
i want to use peripheral and central function.and i can switch it to work peripheral or central state when i need.which stack should i use.s120 or s130.
I am using CMSIS RTOS (RTX) to implement an application for the NRF52 DK. I have found an error in the SVC handler that results in a hard fault when calling a soft device...
Hi all,
I was trying to use the S130 Softdevice but the uart peripheral doesn't work properly... I am trying to send three bytes, but only one appears. Flow Control doesn...
I am using a mutex to protect a serial debug printout.
Is it safe to use sd_mutex_acquire in a blocking manner, provided it is only called from main and softdevice callbacks...
