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.

Hi,
We are using our own custom nRF52832 based board, with revision B silicon however we are having trouble getting trace functionality to work.
Our code uses the Nordic...
Hi,
I am going to design a new product around nRF51422 and I am planning to buy the nRF51 DK but I am really confused about the sw I need for development and additional...
I found this recent Q&A very helpful on the topic of reading voltage on analog hardware pins via the ADC: devzone.nordicsemi.com/.../
In that Q&A, a helpful Nordic person...
I want to use the MultiActivity Example with the nRF52 with GCC and Eclipse.
In the documentation I ve read that S130 and S132 are supported, but in the directory of the...
When I using the UART port, if I float the port after init the UART it will restart the code, is it need a external pull-up resistor? How about the value?
A quick one, where do I find a list of the err_codes? I have had a look in the documentation and I was expecting to find a table of them, but I couldn't locate one.
Thanks...
Hello!
I am trying to send a notification to a peer device when a certain event occurs. To do so, I'm using the same procedure as with every other characteristic with enabled...
I used the example of the ble_central\ble_app_uart_c and ble_peripheral\ble_app_uart.
It seems no problem for operation when I check only this example.
But I modified this...
Hello Everyone ,
I ahve deveoped the custom board using NRF51SOC and i have flashed the custom board by usign P20 Connector referred below figure now i would like to debug...
If I let the SoftDevice write to my variables directly by having the characteristics point to my app's variables through BLE_GATTS_VLOC_USER - when are these variables actually...

Hi,
In S130, both central and peripheral modes are enabled. How do you enable just the peripheral mode and not the central mode for S130 so that less RAM space is used...
