I would like to source a compact BLE board to act as a lock controller developed with with a matching transceiver for use in a fob and an app.
It would toggle the pio and...
Ok so here is the issue. I was trying to build a simple application which is described in the tutorial for characters. After building an advertisement and understanding the...
I was working with IAR and SDK10.0 before. For some reason I have to transfer my project to Keil and SDK9.0. My program worked well for the old settings. While keeps got NRF_ERROR_SOC_NVIC_INTERRUPT_NOT_AVAILABLE...
Currently we are considering whether we should use external Flash Memory or NRF52 Internal Flash.
External Flash memory has a lot of drawback in comparsion with internal...
Suppose there are 10 BLE peripherals in a room and one BLE Central,then is there any way i can get the list of available peripherals[name or id.. etc]?

I am using SDK_11 s130 on nrf51-dk. When err_code is any value other than NRF_SUCCESS, APP_ERROR_CHECK(err_code) will cause nRF51-dk board to reset. How can one get APP_ERROR_CHECK...
Hello All,
I have problem with ble_app_uart which are not support DFU services.
When I am implement both services device will not advertise. and when ble_nus uninitialized...
Hi, I need to read an analog signal 100 s/s which takes 68us at 10bit. There is very little computation to be done once read probably about 10us which I can do to the previous...
I am experimenting with calling sd_flash_write with waiting,
if it returns NRF_ERROR_BUSY, just try again, and then return either success fail
void flashWrite( uint8_t...
Hey ho,
I'm new to BLE and Nordic. I'm a student from Germany and i want to realize one simple function with Arduino (RedBear Blend with nRF8001) and Android.
I want my...
Hello,
We've heard that the BLE transmission packet length may be increased beyond the limit of 20 bytes in a future version of the S110 softdevice. Would you let us know...
Hi
I struggle to understand mechanisms of switching particular subsystem of nrf51822 off and on again in order to consume as little as possible current when MCU is put...
Hi
I have an ADC that just recive, but i will need to make an buffer that makes tx values and just send them to a output pin.
So I wonder how i should code this and if...
I have made custom compiling environment using gcc. I precompile some parts of my software and send to team members .o files what they use in their project so that they don...
Hi, I am using an nRF51822 EK board to develop a custom application and I was wondering about the usage of the SoftDevice. Under what conditions should I use the soft device...
I have recently updated my DFU code to use the source files in SDK 6.1 to be able to OTA upgrade the SoftDevice and Bootloader. I've been able to get the Application to reliably...
Hi,
I am a newbie and would like to build a solution that combines nrf51822 with Arduino. Is this possible.
I find that there are many nrf5001 + Arduino solutions, but...
Hi,
I try to use APP_ERROR_HANDLER(err_code) with a custom error code ( for example 25) in a custom function. Error code reported is correct, but error line and filename...
hello,
Have any example about how to use "CHANNEL_IN_WRONG_STATE" ?
I don't know how to use it. and also don't know when softdevice return this even.

I am having an issue with pin changes triggering interrupts using app_gpiote. I've set up app_gpiote to watch pin 30 and trigger an interrupt on low-to-high or high-to-low...
Folks,
I'd like to use the single UART peripheral in the nRF51822 in interleaved fashion to support two serial "ports", e.g., sets of GPIO pins dedicated to separate serial...
