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 y'all
after having successfully created my own service, similar to the Uart service, I'm now trying to implement security.
As far as I understood, best practice is...
Hi.
I loaded the ble app uart demo and added some bits of code to read some i2c sensors.
I also added a buzzer which buzzes on powerup (simple for loop).
I would leave...
I'd like to (re)set my characteristic's value to Zero. (after my services and characteristics are set)
I tried to search methods that can set value of characteristic when...
Hello,
is it possible to use the RSSI value of the NRF51822 for collision avoidance?
How long does an RSSI measurement take?
I'm trying to implement a discovery protocol...
Hi all! I used PWM module of nRF52832 to create the PWM but i don't know how to update new value to duty_cycle. This is my code. I used Button (Pin 13) to set a new DUTY_CYCLE...
I am trying to set custom value to advertising address. The code snippet is below. I am getting error code 0x10.

Hello,
I have a question about stack usage. I use nRF51822 SoC, 12.2 SDK & IAR 7.60.1. I am interested in stack usage. Have you done any estimations? Or may be you have...
We have a BLE application where we need hopping through nodes. I have shown below how it looks like. We don't want mesh network because we don't require node to node communication...
i use nrf52_DK to debug PDM with a digital MIC, and select the P0.09 for the PDM clk, but i have not see any clock signal output, is it right? and i also haven't see the convet...
Say I have 3 records, then I delete them and collect the garbage. If I try to save a new record again, it will be saved with a record ID 4 , but it should be back to 1 after...
