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 modified the nRF51 SDK_v5.1.0 .36092\Nordic\nrf51822\Board\pca10001\s110\ble_app_hrs proj and downloaded to my self-made pcb,and it worked well. Then I want to update to...
Hi there,
I'm using an input GPIOTE based on SDK11. The interrupt is consistently being fired. On the other hand, if I use "if(Pin_6)" to check the trigger, it does not...
I am trying to use SEGGER_RTT_printf with SDK12 in eclipse.
I have added the appropriate lines to the makefile and SEGGER_RTT_WriteString works fine.
My Makefile lines...
I followed this blog entry ( devzone.nordicsemi.com/.../) setup IAR to debug in monitor mode (by adding Jlink_monitor.c, jlink_monitor.h, jlink_monitor_isa_iar.s, add EnableMonMode...
Hi,
In our project we need to store data onto the internal flash memory.
The data that's stored will be transferred and modified via "BLE uart service". When I tried...
Hi guys,
I'm working on an nRF52832 chip (PCA 10040) with softdevice s132 (v3.0.0) and I'm facing with a big problem; in my project I use an spi (instance index 0) and an...
Hi,
we have the need to develop an application that needs a precise second counter over time.
Our firmware is using the S110 SoftDevice (v8.0.0) and SDK v8.0.0 to perform...
Hi!,
I'm trying to compile GitHub examples, for example this github.com/.../nrf51-ble-tutorial-service
I cloned it into nRF5_SDK_12.1.0_0d23e2a/examples/peripheral....
Hello,
I have custom board with nRF52832, and I want to have possibility to DFU over UART.
I tested example bootloader (nRF5_SDK_11.0.0\examples\dfu\bootloader\pca10040...
I am using nrf51 SDK v.12.1.
And I found NRF_LOG_INFO("BLINKY START\n");
where can I find this log?
Is this different from SEEGER_WriteString or something?
Hi
We are using "gcc compiler" to compiler our programs. To download our programs we use "nRFgo Studio" app.
From the above image, when we load SDK into the device...
Hello,
Consider this scenario:
The client successfully writes to a characteristic by the application code can't use the data sent so it would be usefull to signal the...
Hello,everyone. Now i have the board nrf52832 and i want it to enter the low-power mode but keep the the advertising. Now the measured current is 160uA, I think there should...
Dear All,
I apologize in advance if it seems that the question has been already posed but it is still unclear to me.
I have a pin (SIG_OK) and I want to read its logic value...
On the nRF51 DK there is a MM8130-2600 connector. I suppose it is used for connecting coax cable when tuning the antenna(?)
The connector is quite expensive, though. Is...
