Hi,
I'm running into what looks like a software link-layer issue on the nRF54L15-DK that I'd like a second pair of eyes on. The same firmware works end-to-end with iOS...
i2c_write_read() returns -5 (EIO) immediately when writing register 0x01 to the sensor. Logic analyzer confirms the sensor clock-stretches SCL for ~14µs+ after receiving the...
I recently completed a field-upgrade path from an nRF5 SDK 17.1 application (with the legacy Secure DFU bootloader) to a fresh NCS-based firmware stack, while preserving user...
Hello,
We are currently evaluating BLE Gateway (CIS, BIS) development using the nRF5340 Audio DK.
We would like to ask whether bidirectional CIS streaming is officially...

I connected the programming header as described in "nRF6930_Beacon_Ref_Design_UG_v1.0.pdf" 5.5.4 Programming interface. I was trying to program Beacon Kit but failed many times then I compared it with…
Hi,
I have written SD & SDHC card routine for reading, writing and erasing data from SD card. It used the hardware SPI of nRF51822.
NOTE:
1)Define the PINs of SD card first before initialing.
2)Define…
There are several types of write operations, write request with authorization, write request without authorization and write command. You can see message sequence charts for those messages here and he…
Here is an example of a hardware setup to measure the voltage on a Lithium battery with a voltage divider and a connected capacitor. The Lithium battery typically has a voltage range of 2.7 - 4.2 V and…
