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...
hi.
as far as i know, dfu for softdevice 110 can be carried out over ble, while s120 can not. so i have to implement a bootloader for an app with s120 through wired.

Hello to all,
Since a couple of weeks I have a problem in a program which consist of three parts:
1.- a Timer to make a pulse train by interrupts
2.- a program to control...
Hi,
Im using SD5 and after some time (every time different) of transmitting HRS data the SD stops apparently, because there is no more connection with my Android phone...
I am trying to apply the new features in the latest soft device s110 v7 to the firmware of my pca20006 bluetooth smart beacons (nRF51822 Bluetooth Smart Beacon Kit Firmware...
I have Eclipse CDT set up for debugging the ble_app_proximity sample code on a Mac. I can start the GDB server on the console and connect to it. Flashing the code seems to...
Do you a way to get better range for BLE.
Distance outdoor Number of samples per second using the development kit. ( 12 bytes)

I'm learning about GPIOTE and PPI and looking at an example I come to the following code but now it act incorrectly. So as you can see I'm enabling the interrupt for GPIOTE...
I am working with the nRF51 Software Development kit for the nRF51822 Evaluation kit
There are some kind of type qualifiers such as __I, __IO appearing in the header, e.g...
I am following nRF51822_Evaluation_Kit User_Guide v1.2.pdf (page #9) to run Heart Rate sample but I am unable to get an expected result (LED 0 should be lit) when I am pressing...
Once I downloaded Soft Device 110 (s110_nrf51822_6.0.0_softdevice.hex) into my Evaluation Board's chip I ran nRFgo Studio and saw that the size of the Region 0 is 80KB and...
My Board PCA10024 (nRF51822 Chip QFAAG0) consumed at least 18mA with external 3V battery.
The nRF51822 chip itself consumed only 5uA in sleep mode.
What's go wrong? So a...
Hi,
in, for example, the multilink example app, central role.
I would like to disconnect a peripheral role device once a notification has been received...
... is it correct...
I am using a stripped version of ble_app_hrs of SDK5.1 with Softdevice 6.
I stripped all services from ble_app_hrs except the DIS. ( so removed battery, hrs, buttons and...
Hi,
question is probably trivial, but I cannot find answer for second hour, so maybe somebody know, how to set that same address for Application downloaded from Keil and...
