The e-mail contains news of a new use of the nRF9151 module but uses the word "proves" and as an English language Cambridge qualified teacher I must mention that the word...
Issue description
I am using SAADC in single-ended mode with 3 channels (0/1/2). Measurements are performed by enabling SAADC, running offset calibration, configuring the...
Hello,
I have an application running on legacy NRF SDK and using the nRF5 bootloader, which has below flash sectors, 0x00000 - 0x026000 - Soft-device section 0x26000 - 0x0D9000...
Our custom product, based on the nRF52832, is undergoing certification. The testing laboratory requires that only one BLE advertising channel be active at a time—first channel...
Hi there,
We have a mass produced product with a modified secure bootloader (from SDK17). This BL has BLE and USB and we bolted on an SPI flash transport for OTA updates...

I am ready to start creating my model, but was wondering if there were examples...
I run the system_off example without the system actually going off, by removing all the calls to start the system_off worker. Instead of going to off, I let the system enter...
Hello
I played with the mcuboot_recovery_entry bare metal dfu sample. I noticed that if I sign an application image with an invalid key (invalid on purpose), the firmware...
I have been reviewing the antenna section in the datasheet of the BLE audio SoC nRF5340. The datasheet mentions a single-ended antenna output (on-chip balun). Could you explain...
Hi,
When the firmware is run in debug mode (J-Link connected), the system always works correctly. BLE initializes properly, and all sensors function as expected.
When...
