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...

Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
I changed only source clock part to internal clock and it doesn't do advertising. When I debug it, it starts to run. When I finish the debug session advertising stops again...
Hi,
I've built a custom board with nRF52832, without other MCU like PCA10040. I use a FT232RL to bridge the USB to nrf UART, flashed nrf5 uart connection firmware ble_connectivity_s132_uart_pca10040...
Hi, I using nrf52810 with custom BLE profile and 4 sec advertising + continuous RTC. Device is battery powered (750 mAh) and PMDC motor equipped. Most of time (90% of day...
Hi,
I am designing my custom board with the nrf52832, which would perform the BLE and I2C functions. I wonder what necessary and basic peripherals it needs, like crystal...
Hi,
I would like to synchronize 2 Sensors with one dongle. So the problem is that we have two sensors and we want to start the measurement at the more or less (1 ms) exact...
Hello,
I am new to BLE as a technology and have a question regarding how Peer Manager handles bonding.
As I currently understand, the function of bonding is to enable...
Hi,
I want to use nRF52832(PCA10040 board) to communicate with nRF24L01+. I program the example application( \examples\proprietary_rf\esb_ptx)(SDK v15.0.0) on the board...
Hello. I'm developing an application with a custom bootloader and I'm using "settings" data structure placed in FLASH. Because we can erase only full pages, the first page...
Hi.
I want to implement multirole on the nRF52832. I want to advertise beacon data while scanning. So, I modified ble_app_uart_c in the ble_central example. Below is a description...
Hi,
I try to program hex file with openOCD. The flash part is written without any problem. OpenOcd only fail to write the UICR registers beyond 0x10001200.
However it...
