Hi!
I've been using PCA10028 for a long time and I had some bricking issues but I've managed to un-brick it with "nrfjprog --recover" and everything would work again. ...
Hello,
I am working with an nRF52 and two sensors using TWI. My code is based on the TWI_sensor example from SDK 12.2. I made an interesting discovery today when trying...
Hi, I am new to creating boards with RF capabilities, so excuse me if I get anything wrong or missed something. So, going over the reference layout for the QFN32 version of...
I am trying to use UART1 on nRF52840 to communicate with another device on a custom board. I am using Zephyr. I have successfully compiled code using the function uart_poll_out...
hello Nordic
i am using nrf52832, sdk 16.0,
i have a system which need to react to multiple external interrupts on multiple pins
i see that when ' nrf_drv_gpiote_in_init...
The nRF52 SDK is limiting the transfer size to 255 byte even if the HW supports bigger buffer.
This is due to a data type that is defined as uint8_t:
typedef uint8_t...
Hi,
I'm using nRF52-DK evaluation board, and ble_app_template_pca10040_s132 (from examples of nRF5_SDK_17.00.9d13099)
I'm designing an android smartphone as a central...
After moving to v1.3.0, my build fails, because the imgtool can't find the module cbor. I see some updates for zephyr that indicate cbor.py is now required, and it's included...
I would like to tightly integrate a nRF24L01+ with my microcontroller. I have read as much as I could, and copied as closely as I can, but the best layout required moving...
I have pretty much gotten my application fully ported and working on nRF52832. I am now looking at adding in DFU for OTA updates.
Can you confirm my understanding, based...
Hello,
We are trying to use the usb wakeup feature while also using the usbd as a serial port (over usb).
The rwu is registered on initialization in our firmware using...
Hello,
I am using a nRF52840 dongle to communicate between a laptop running Ubuntu and a phone running Android.
Right now I set up a UART-BLE communication using an...
Hi
I've been developing using an NRF52 DK and have moved onto my own design board, I have one small problem which I'm unable to replicate using the DK. On my own board,...
I have tried to study the behavior of the QSPI and the external flash. I noticed that the QSPI_CONFIG_READOC and QSPI_CONFIG_WRITEOC settings in sdk_config.h cannot be set...
Hello,
I'm developing AoA/AoD feature, accoring to manual, the nrf52833 uses S0CONF and S0MASK to automatically determine if the part S1 exists in the packet or not. I tried...
Hi everyone,
We are designing a low power PCB based on the nRF52840 BLE. At the moment the device is advertising with an interval of 1s and a timeout of 3min (advertising...
