Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

We would like to be able to calibrate the rRF9E5 ADC
Our proposal is to permanently fit voltage dividers, each using two precision resistors, on two of the ADC Ports and...
At some point in the past I had nrf51+gdb+breakpoints working just fine. I even have a bunch of __BKPT() calls in my various error handlers to trap into the debugger.
At...
Hi,
I'm trying to program nRF51822 Beacon Kit using nRF51DK. I'm trying to load the example ble_app_beacon to the beacon kit. After uploading SoftDevice 7.1.0, I try to...
Hello
I'm using the nRF51 DK and I have a UART over BLE link set up between the board and a phone with the nRF UART app. I'm trying to get the board to execute a particular...
Hello there guys i been reading your 100 pg PDF for awhile now and im yet to understand or realize how is it that i add/place/create a payload or data to send/Tx via Master...
I am interested in writing a BLE central that reads data from multiple BLE Nordic sensors. The BLE central will be running on Embedded Linux which uses the BlueZ stack.

I'm currently trying to send streams of data from an Android app to a nrf51. However, at some point, Android side writes to the...
Hello,
Our device based on nRF51822 with SD110 v.8.0.0.
The firmware use defined area in top of the flash to store some data.
The "RAW" functions sd_flash_write and sd_flash_page_erase...
Hi Team,
Is it possible to scan on one channel and advertise on another channel?
Say node-A will scan on ch-37 and advertise on ch-38 while
node-B will scan on ch-38...
I'm trying to use the NRF51DK to talk to this EEPROM ( www.st.com/.../CD00290537.pdf) . I've started by trying to modify the twi sensor example. One of the things that's different...
I am new to nRF51:
how do I change the softdevice from 110 to 130 in the example project ble_app_uart (and in general) within the Keil µVision IDE.
There is no option...
Hi,
I am developing a product for the 433MHz band. Due to the space constraints I had cut the ground plane to very small and also had to rearrange the components away from...
Hello everyone,

I'm trying nRF51-DK (IoT SDK) with Coap server , (raspberry pi with Coap client by python example...
Hi,
we are using RTC2 with APP_IRQ_PRIORITY_LOWEST. But the code hanged inside the interrupt handler. when we did step through debug, we came to know that in nrf_drv_common...
In nrf52_SDK/examples/peripherals/rtc we tried adding the UART prints and verified. It was working fine for RTC0 but fails to do for RTC1. Could you please give any hint on...
Hello together..
i have a problem with the nRF51 DK.
I tried a little bit with this DEVkit i.e. copy the blinky example to the JLINK storage.
This works fine.
Regarding...
Hello,
I am developing a new product using S130 on nRF51822(QFAC). My product use LCD as spi interface and ADXL345 sensor as i2c interface, also test it, works well without...
Hi all:
To saving power I implement the function to read data after interrupt is triggered..

I am trying to set up a GPIO interrupt, and found that whenever Button 1 is pressed, if Button 1 or 2 is pressed later, the app will reset. This is even if there is any other...
Hi.
I want to make a device which can connect each others and communicate with NUS.
I need not to use any other service without NUS.
I made nus_c service which is a central...
Hi
I can't seem to find this in the datasheets, what is the active current consumption of the nRF52832 chip, I'm interested in the maximum expected current consumption...
