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
developer.bluetooth.org/.../runningspeedandcadence.zip
unfortunately the server starts but i'm not able to...
Hello,
On my custom board, I'm receiving chunks of UART data, without flow control, at 115200bps. Sometimes (its quite frequent now... sometimes after 10 chunks, sometimes...
I'm working on a PC application (using nrf51-ble-driver_win_0.4.1 API) to connect a BLE device and discover BLE services.
Today, I'm tying to connect the Nordic dev kit...
When discovering services using nrf51-ble-driver_win_0.4.1 driver, some ID are received with type BLE_UUID_TYPE_UNKNOWN. So I assume they are 128bits. I then retrieve the...
I downloaded the BLE beacon app S110 v7.1.0 to a nRF51-DK board. The current measurement pins were attached to a 10 Ohm resistor.
I observed the AC-coupled voltage at one...
Hi. We've got a chip with a code QFACA10. I am trying to find out if there is the internal pull-down of SWD line or not. It seemed that adding an external pull-down had positive...
Hi all,
I want to know the effect on power consumption of pins input buffer on and off, does there are big differences between them?
Another question is, since there...
Hey everyone,
when i was trying to compile i got this error which says
._build\ble_app_bci.axf: Error: L6200E: Symbol SWI0_IRQHandler multiply defined (by nrf_notification_manager...
i have few question based on nordic i am using N51822.
1: does device goto sleep, while testing i see sometimes device gets automatically disconnected.
how can i solve...
Hi,
what would be a good option to create a BLE device like FLIC (flic.io).
i want to transmit only a few informations to the smartphone like 1,2,3,4 and the device shall...
Hi,
every time i try to call ble_bas_battery_level_update(&m_bas, 1); my application freeze and i can't get any response
Here is what i did:
1- copying ble_app_template_s110...
Hello folks
I have a custom PCB board with the attached layout diagram. I also have our firmware that was flashed on to the Nordic beacon kit and tested. I would like to...
Hello,
at the moment I try to add some more services to my BLE device. This goes wrong with err_code = 12 (NRF_ERROR_DATA_SIZE). With some search in the devZone I found...
I have the nrf51822EK and trying to make it report the speed/cadence of a bike. So far the design is to report the speed every 1 second as a BLTE peripheral device automatically...
Hi,
the ANT protocol defines the channel message rate in a range from 0.5Hz to above 200Hz, with the upper limit dependant on the specific implementation.
What are the...
