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...
I've tried a trivial example (blinky-like, compiled by gcc using proper startup and ld scripts) on nRF52 devkit, but I always only get hard fault.
Debugging through the reset...
The nRF24L01 dataseet V2 (the most recent I think?) states (p.23) that the nRF24L01 can operate on frequencies from 2.400GHz to 2.525GHz . The channel steps are stated as...
I am completely confused by the nRF51 UART. I'm trying to port code originally written for an STM32 (another cortex chip). There, I define an interrupt, enable the RXRDY or...
Hi,
I need to have two different interrupt handler for one pin?
For LOTOHI one handler and for HITOLO another handler, how to do that?
Here is what i did until now...
Hello Nordic and fellow developers
While implementing bonding into an application based on S130 I found it necessary to test on the role of a given connection. Different...
I am getting device id of peripheral on central and then getting it displayed on hypertermianl hyperterminal using ble app multilink perihperal code with multilink central...
Hi Everyone,
I have what I hope is a simple questions. I am creating a piece of hardware that will act as the peripheral to a central iOS app in regards to a standard BLE...
Is there any construction available in the SDK, to achieve printing functions, with an undefined number of parameters ? The classic example :
#ifdef CONFIG_DEBUG
#define...
Hello,
I've ready the final S130 spefication and it states that the advertiser is started as early as possible and that i runs asynchronously to all other roles. Now I...
Calling app_sched_event_put() from the NRF_RADIO_CALLBACK_SIGNAL_TYPE_START signal handler causes a crash due to the CRITICAL_REGION_ENTER() call inside of app_sched_event_put...
is there any code for device which act as master and peripheral other than nRF51_SDK_8.1.0_b6ed55fnnn\examples\ble_central_and_peripheral\experimental \app_s130_demo\pca10028...
I have a simple nRF51822 BLE application where a voltage is read by ADC periodically, and several values are sampled and averaged. However, from time to time, I get another...
Hello All ,
I am working on nrf51822 with sdk 7.1.0 and softdevice 7.1.0 .Earlier my ble connection was working very good with no disconnection anytime unless i disconnect...
Now I'm working with MCP 3.9.0.
When any device is connected, characteristic default values are not 0's. Can they be initialized in any way? It is a little bit annoying when...
