I've just trying to get SPI working, everything is compiling OK but when initialising the SPI, when the line below is hit, /* Clear waiting interrupts and events */ p_spi_instance->p_nrf_spi->EVENTS_READY = 0;
I end up in here: void app_error_handler(uint32_t ... (more)
For my application I need to identify the peripheral source advertising packets are coming from. How is this best done with BLE and SDK 7.1? I would prefer not to set a a different device name for every source.
What is the role of pstorage exactly?
In what situations do you use pstorage?
Where is pstorage the area occupied by memory?
Hi, I bought the nrf51822-beacon kit and nrf51-dk including TC2030-CTX-NL connector for connecting them each other through the Debug out pin on the nRF51-DK.

I know I have seen the topic on the forum, but can not find it. What changes need to be done to a example project designed for a softdevice 110 to convert it to a softdevice 310?
Thank You, Glenn
I've spent 4 days now (!!) on getting a "Hello World" project to work in eclipse with GCC. I guess something around the startup-code is setup wrong in my very simple project but I don't know what ... (more)
I would like to know if it is possible to log realtime sensor data to flash while advertising. I would like to have a device which transmits real time ECG data over ble UART to an android device when in ... (more)
Hello I have a nrf51822 mbed kit PCA 10024 V1.0.0. When I connect the kit to the PC (Windows 7 64 bits) the Mkit enumerates as an MSD named MBED:
I updated the firmware to version 2018following the ... (more)
This is factor 2 to what I read here. How can they achieve this? Where is the trick? http://www.dialog-semiconductor.com/p...
Hello, I'm using nRF51822-mKIT for a research.
To verify ADC readings from analog input, I've connected P0_5 to GND and ran the following code:
uint16_t adc_result; NRF_ADC->INTENSET = (ADC_INTENSET_END_Disabled << ADC_INTENSET_END_Pos); /*!< Interrupt enabled. */ // config ADC NRF_ADC->CONFIG = (ADC_CONFIG_EXTREFSEL_None << ADC_CONFIG_EXTREFSEL_Pos ...
I was just wondering what the sequence of events would be in the following scenario:
A S110 peripheral device (GATT server) has a characteristic with write access and notifications enabled (by the GATT client). The GATT client performs a ... (more)
I have looked over the entire site and can not figure out what is needed to change the Smart Beacon Kit firmware and uploaded it to the beacon.
Is there a way to recompile the source firmware (what tools do ... (more)
For my project I would like to use this bluetooth module: http://freqchina.en.alibaba.com/produ...
Does it resist 4 bar pressure? Does it resist circular motion > 100 rounds/second (radius 7cm)? (And how does that may effect the bluetooth signal..?)
I am trying to connect to a peripheral through s120 central and vendor has a 128 bit fixed UUID
I am trying to add it on central using sd_ble_uuid_vs_add(...,...) but it is not working and everytime I am getting charachtreristics ... (more)
Is anyone using the third-party BLE module from Taiyo Yuden? If so, where did you find the recommended footprint?
Taiyo Yuden's website only gives very limited information about the module. I have requested further info through the form on ... (more)
Hello, I am working on an application based on the "Motor control example". However instead of just setting two different values for the duty cycle I am trying to either increase or decrease it for every button press. I am ... (more)
Hi, I would like to know how I can immediately detect when a connection link is loss either from the central or peripheral. I need to know which error or notification to look out for when a data exchange fails ... (more)
What changes need to be made to the ble_app_template example so that it will succesfully run as a central (with S120).
I'm developing a security scheme in which the firmware verifies that the nRF51822 is the same as the one in the factory to which the firmware was installed, i.e. whether it's running on authentic hardware ... (more)
Hello! I'm trying to use s130 as peripheral. I flashed nrf51822 with s130 stack. Opened peripheral example and build it with .ld file for s130. After it I flashed this project into the nrf51822. Started nrf51822. in Nrf Master ... (more)

Hello. Can I use flash_write example functions (nrf_nvmc_write_byte, nrf_nvmc_page_erase) after open channel on background scanning? Regards, PW.
The nRF51-Dongle has these 20 pads which I think correspond to a debug port:
On the schematic, it looks like these feed into JTAG signals:
My question is: can I solder a connector onto these pins and use the ... (more)
What exactly are the "glitch" issues with the PWM master library? I see there have been some recent updates, but no clear indication as to what issues remain or have been resolved? I take it the 4 channel (non-glitchless?) version ... (more)
I am trying to set up a GZLL star network on the 51822. I understand that a single GZLL host can support up to eight devices but whenever my host attempts to communicate with more than 2 devices each communicating ... (more)
