I have the issue that my Zigbee device reports the error "Production configuration is not present or invalid (status: -1)". I followed the guide from this( https://docs...
Hi,
I am using an nRF52840 as a Zigbee NCP. I have built the firmware myself using nRF Connect, and I am also running MCUBoot. Sometimes after some usage, the chip starts...
Hello everyone,
I am testing out I2C on the nRF54L15 for a custom PCB project.
I first tested a simple mpu6050 sensor on &i2c21 on pins P1.11 for SCL and P1.12 for SDA...
I have a bit of an unusual use case where the nPM1300 is quite ideal but need to use an external charger for the battery instead of the internal charger. The nPM1300 fuel...

Hello, I would like to know if there is any way to avoid bootloader start in secureDFU firmware transfer. All the checks on init file and control point are on the application...
My DFU is staying in the bootloader, even after successful download of the application package.
I have modified the secure bootloader for my custom PCB (removed the GPIO...
Hi,
I'm trying to get OpenOCD flashing to work on Windows using the FTDI 2232H adapter and an NRF52 target. I found this site:

Hello,
I am trying to read multiple registers from a slave of i2c.
The values that I capture are the first value repeated in all the buffer.
The number of readed reg...
Hi,
I would like to use ping pong mechanism to prevent faulty application update on nRF52840. Is there a way to build a single image to run at 2 different addresses? How...
I have OSX Sierra, VMWare Fusion and Windows 7 available.
I do Arduino (Teensy) dev, staying on the OSX side.
I want to use the nrf52 chip as a MIDI over BLE conduit ...
Hello,
I have a PCB with a NRF52 powered by batteries. We need to be able to plug the batteries, then program the device and never remove the batteries.
We noticed, that...
