I am relatively new to embedded and am wondering if there was a "best practices" guide / checklist for production deployment somewhere. Things like making sure you are using...
Hi. I'm trying to write a simple MQTT app. I am consistently getting these KConfig errors to do with variables I'm not using, and I have tried to set CMake to ignore these...
Good day,
I've developed a board with a MDBT50Q on it. I'm using the Reg0 DC/DC and LDO Mode Disabled reference circuit ( https://www.raytac.com/download/index.php?index_id...
Hi,
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...
I am new to nRF programming. My "far away goal" is to make a BLE sensor mesh with a centralised data collection.
Currently I am deciding what libraries to start playing...
Peripheral device has 2 services,but central can find only 1 service(0x1001).
I want to find other service(0x0001)
According to the message seems to be looking for 0x1001...
Hi,
I'm using the nRF51 dongle with nRF SDK 12.3.0 and the S130 2.0.1 SoftDevice to implement a BLE central. The dongle repeatedly connects to a BLE peripheral, performs...
I'm running the PB Remote Client on a PCA10040.
I have 2 servers running on PCA10040 boards.
Watching the log whilst debugging the client, I receive the following: ...
Hello all,
I am new to nRF platfrom, I am working on a protect which contains multiple BMD-200 modules with nRF51822 controller. It has to transfer some data via UART,...
Per this blog, I understand that the nRF52's ANT pin must be matched to 50ohm via L1/C3 and that the antenna must be matched to 50ohm. Hence a trace with 50ohm characteristic...
Hello, the title is pretty descriptive.
I've tried to read through previous questions and got a rough idea but decided that it would cost too much time for me to explore...
I am working on a ble application using an nRF51822 that requires low power consumption. I'm curious if on average the observer or the central role will consume less power...
We have our own custom board using nRF52832 (via Laird BL652 module). Until recently, we have been programming our application, bootloader and softdevice using the PCA10040...
SDK12 and SD 132 v3.
I have my code working for HVX from the peripheral. I can HVX send up to 80 bytes on one characteristic in one call (ATT MTU was set to 83 and DLE...
The NRF52 product spec suggests:
"The input buffer of a GPIO pin can be disconnected from the pin to enable power savings"
I've found that gpio.h provides the function...
Here is a snippet of my debug log:
