Hello,
Is there any USB device stack available for bare metal development on the nrf5340 using online NRFX lib. I am trying to implement a USB CDC device class.
No issues...
These seems like another dumb question. First off, I am aware that the nrf21540DK is the nrf52840 with the FEM tacked on the output.
I know I can select the nrf21530DK/nrf52840...
Hello,
I have 4 nrf52840, 3 act as peripheral and the last is the central.
The peripherals are identical hardware with various sensors using the same FW. I order to...
Hello,i've recently bought a nRF52840 dongle to sniffing BLE packets with wireshark. I regret to inform you that it don't work roperly, in my opinion. In fact, you will find...
I just fired up our most recent custom boards with nRF9161-LACA's, and tried to compile modem shell application for RTT.
I noticed the RTT is disabled because HAS_SEGGER_RTT...
Hello
Awhile back I profiled my battery using power up app @ 4C 25C and 45C for a battery between 2.75V and 4.2V battery model is attached in zip.
The profiles themselves...
What is the operating and storage temperature range of nRF52840-DK development kit and USB dongle? We need to use these evaluation boards at a temperature range of -20 to...
Experts,
I'm trying to use NRF52480 Dongle to communicate over UART serial port. On the forum I found that pins 1.10 & 1.13 are used for TX/RX. I learned that flow control...
If i buy a raw nRF52832 chip and design the circuit by myself, how can i pre-programm the serial bootloader in it? So i could use the FTDI Basic (or an FTDI Basic -like device...
Hi,
Is there any way to change the advertisement name before switching to DFU mode?
I have a custom app that reboots into DFU mode (via NRF_POWER -> GPREGRET ). I want...
Hi,
I've to design an alimentation with capacitors to keep energy and filter current peak. To do that I need to know timing for NFC peak current. Do someone have information...
Hello,
I have a running system constituted of a central and 15 peripherals using nRF52840 devices. The central is set to scan the peripherals for 5 seconds then stop and...
Hello,
I'm implementing a beacon scanner with nRF52 using nrf_ble_scan.c. After the scan has been configured with no filters, no advertisement reports are returned to the...
Hi,
The definition of the COEX1 pin looks to be really interesting for applications that need a reliable time reference. A 1PPS GPS output is very useful; absolute accuracy...
Hi
Our nRF9160DK card seems to have stopped working. We attached a sensor to the card (We might have connected the reset pin on the P7 strip) and now I can't start any program...
I was trying to make sense of the serial support in mcuboot, but it uses a protocol and format I don't recognize. I expect they're generated by the Apache Newt tools, since...
I am designing a board based on the nRF52832 and wanted to examine the reference design files 'nRF52832-QFAx Reference Layout_v11.'.
However, The the downloadable files...
Hello!
I am using a nRF52832 with the S132 v4.0.3 softdevice. But I get an error from the softdevice via softdevice_fault_handler.
It gives me id 1(which suggest a NRF_FAULT_ID_SD_ASSERT...
Hi,
I'm using SDK 15.2. The bluetooth disconnects when I enable notifications on nrfConnect. This happens only if I increase the number of bytes to be sent. I'm writing...
hii,
i am currently using light switch example proxy server and proxy clients.
here i am using 3 boards ,2 board(node B &C) are programmed with 4 generic onoff servers...
Hi,
We have a bluetooth product which uses Nrf52840 as the MCU. It composes of a peripheral and a central device of which connect with each other via bluetooth and they...
