We are in the process of finalizing the RF transceiver chip for custom protocol development.
Please suggest the suitable chip and any reference implementations available...
Hi Nordic Team,
I'm looking to use the UICR->OTP region ( One Time Programmable (OTP) memory region within the User Information Configuration Registers (UICR)) on the nRF54H20...

Hi Nordic Support Team,
I'm currently experimenting with Channel Sounding using a couple of nRF54L15 boards.
I am trying to obtain raw I and Q samples so that I may analyze...
We use several Nordic chips in our BLE sensors. We bond to the devices from Android, connect to update configurations, then disconnect such that the device then advertises...
There are a bunch of questions ( 1 , 2 , 3 ) about handling the NRF_ERROR_INVALID_STATE code returned by the soft-device. This code is returned when the stack is in an "Invalid...
Hi
I have working application on SDK 11, contained with bootloader, softdevice 130 and application using BLE. Is it possible to upload new application and softdevice from...
Hi,
There seems to be some pieces of new code (updated example and some components) for ble_app_mtu_throughput example embedded in the softdevice packet 5.0.0-3.alpha....
I've recently migrated from SDK11 to SDK12.3 to take advantage of the low power option. However I still am having weird issues with power consumption. I have a feature which...
I have merged all the 4 file's together (app.hex, app_valid_settings.hex, softdevice.hex and dfu.hex).
Then I uploaded the custom app with dfu services enabled using nrfgo...
Hi there,
I'm porting an app from NRF51 SD130 to NRF52 SD132, both with sdk11. I do the usual stuff, like changing includes, freertos ports libraries, etc, and everything...
Just a general resource question. The Softdevice uses RTC0, FreeRTOS (by coded default) uses RTC1. So in order for the SDK ble_conn_params.c to run properly I have to link...
I was able to add the Device Information service as well as a proprietary service using a 128 bit UUID. I modeled after the ble_peripheral uart example. However when I try...

My application was at the point where I needed to add DFU. Following the examples and SDK doc, I added the files and code needed. It would NOT advertise...
We recently moved from SDK11 to SDK13. We run out of memory when adding custom services & chars to the S132 v4.0 softdevice. Increasing the app start address in the linker...
For the record I have been struggling with migrating a project from S110 @ nrf51422 to S140 @ nrf52840.
Quite by accident, I found this "nrf51_to_nrf52840.h", what does...
Hi , Everyone!
Now i have the board nrf52832 and i'm conducting my DFU.
My DFU is to update softdevice and application.
Here is detail about my problem:

Hi
From s140_nrf52840_5.0.0-3.alpha_migration-document, it is mentioned that the L2CAP API has been completely removed. Are there plans to re-expose the API? We have exposed...
I'd like to clock the nRF52840 at the same frequency as my converters. Is there any problem with using a somewhat different frequency than the 64 MHz (or 32mhZ) crystal? If...
