Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

Hi,
We have a Lattice Ice40 UltraPlus FPGA, SPI FLASH, and nRF52832. We would like to be able to include the FPGA's binary image in our DFU package but it is about 110kb...
Hi,
We are using SES on Windows to program a nrf52832 device with a SDK 16.
We are having problems with the Secure BLE DFU. We are able to perform the DFU on our devices...
We're trying to minimize power consumption on our custom nRF52840-based board and we have some questions about the behavior of HFINT and HFXO. The specification says this...
Hello,
I am currently evaluating concepts on how I can power my nRF52832-custom-board with a LiPo-battery, in order to get a good tradeoff between lifetime and form-factor...
HI Team,
We are using the nRF52840 DK for our development purpose. We have some issues with USB J2 connector and unable to connect the on board debugger. We have tried...
Please note about 9 days ago another user reported similar problem but is his case LED3 and LED4 were blinking. In my case after reset I see LED 3 blink and then about 30...
It had been working fine until just this moment.

I'm using the following code with the intention that when the RDY pin goes low, it will wake up the processor...
Hi! I'm currently using the nrF52840 DK to send numbers by BLE. I have 2 questions for you. 1. Can I send negative values? ex. -1, -2, -3 2. Can I send decimal values? ex...
Hi Nordic Support
I have been working to port a blinky variant project and have found previous threads useful for guidance. I'm working with Segger Embedded Studio and have...
Hello,
Is there a way to multicast messages from BLE client to multiple servers? I know mesh does the same job but we are exploring a possibility to do the same using standard...
hi,I am working with nrf52832 board. I want to send the multiple beacon at a time(same instance).
can you please suggest me at a a time how many beacon we can send out(exact...
Let me first show what parameters I am choosing for calculating the data rates :
Conn interval is 7.5ms and connection length ext is off meaning it wont extend the connection...
Hello,
Application crashes at " nrf_sdh_enable_request ()" without returning any error code. Execution up to this seems fine and I get RTT debug prints. I have also tried...
