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...

Hi,
I am programming nRF52840 dev kit (SDK16) as a peripheral with S140. Smartphone is central.
data needs to be transferred between both.
I need the dev kit to consume...
Hello, I’m using nRF52840 with SDK 16 and SD 7. My purpose is to save as much power is possible using high-frequency clock (32MHz) only during periodic duties and BLE activity...
What are best practices for updating an nRF52832 via UART from an nRF52840? There seem to be at least two problems to solve:
Transmitting the 832 image via BLE to the...
Hello,
I'm measuring the idle current using a PCA10040 DK, SDK v16.
Finding that the idle current is about 3uA (which I think is correct) after any debug operation like...
Our setup is using a NRF52832 with SDK15.0.0.
While working with a time sensitive external circuit where we both sample the state of the GPIO and enable LDETECT on it...
I have just received my nRF52 development board and I have tried to program one of the pre-bjui;t examples (Blinky). The USB drive on the board appears and if I drag the hex...
Hi,
I'm using an application with FreeRTOS , nRF52833, SDK 16.
When I'm trying to get it into low power (sleep mode) the system still consumes ~4mA
In vPortSuppressTicksAndSleep...
Hi,
I am starting with PPK. Tried some measurements on ble examples and looks like i am doing something wrong. I have aproximatelly 7mA during advertising. Am I doing something...
Hi,
i have load existing program to new nRF52 module. But it shows NRF_ERROR_NO_MEM.
Same old module doesn't show this error. i also reload the soft device. But no improvement...
I'm looking to implement the following security schema:
The peripheral does not have a display nor input capabilities
A smartphone will connect to the device
The peripheral...
I can use the nRF Sniffer to capture packets , but info "Empty PDU" is more and more, I want filter it. Please kindly help me how to operate it. Many thanks!
Hello. I have 3 peripherals connected to 1 central. The BLE_GAP_EVT_TIMEOUT event occurs in Central. Occurrence timing is random, p_ble_evt->evt.gap_evt.params.timeout.src...
Hi,
We are developing a solution with our partner company based on nrf52833 using S140 softdevice.
I would like to change the advertisement power after every advertisement...
