We have been evaluating the nRF5340 and nRF7002 for use in a new product and we are currently looking at our Wi-Fi FOTA options. For reference, we are using an nRF7002 DK...
Hi Nordic team,
We are developing two types of devices based on the Zephyr examples:
periodic_adv_rsp
periodic_sync_rsp
Our design uses the following...
Hello,
I've a battery based device that uses a buck/boost to efficiently use entire battery voltage range (4.2-3.0) . This component have a low quiescent current between...
Good afternoon! As the NRF7002 takes about 400ms to start up from shutdown, we would like to use the very low power deep sleep function for quick startup. Unfortunately, due...

Hi,
I would like to know the difference between the nRF52840-QIAA & nRF52840-QIAA -R7.
What is the significance of R7 here. Not able to find it in any conclusion ...
Hi, I'm working with the DWM3001CDK (nRF52833 + DW3110) and currently using SPI to interface with the DW3110 for UWB communication.
I'm trying to use a second UART to communicate...
i need a help with the attenna design. here is the eagle files, i'm not sure it is fine. i used a Balun BAL-NRF01D3 and my board thickness is 0.6mm. i need to know the copper...
I got the nRF51822 DK and tried hooking up the dongle. I am using Windows 7 32 bit. When I plugged the dongle into a USB port, there is a “JLinkCDCUARTPort（COM19)” added to...
Hi,
My device is always in bootloader mode, even if i flash the sample heart rate application it is not entering into the application. Actually, before it was working fine...
Hello,
I am planning to develop an application in which I need to do some image processing (probably using open CV libraries), and I would like to know if the nRF51822...
I see in the example code there is
#define FLASH_PAGE_SYS_ATTR (BLE_FLASH_PAGE_END - 3) /**< Flash page used for bond manager system attribute information. */
#define...
I'm using NRF51822 and I have some question about the ble connection:
according to BLE 4.0 spec, when Tsup(connection supervision time) reaches, connection lost is considered...
Hi
Do the latest sample apps (for example, Heart Rate) which do not required bonding behave as follows:-
make connection from iphone
enable notification
check...
We have done some test on how fast we can receive data from a BLE service, which is around 6KB/sec and this is all fine. This test was fairly easy to make, as we could just...
I have implemented my own I2C driver and I am getting issues with NACKs.
On review my code is doing what twi_hw_master.c is doing.
I then went looking for a Nordic sample...
We have developed and certified a module which uses the nRF24l01+. We spent a good amount of time tuning the antenna circuitry which has resulted in very good range... in...
Hi,
how to get into the bootloader mode without pressing any button, when some application is running? I also tried it with setting the NRF_POWER->GPREGRET but it is not...
I am looking for a minimalistic schema design using BLE for collecting data from i2c (twi) sensor and sending them over blue-tooth to the receiver. I need the following features...
Hello,
I would like to know if there are any restrictions in the amount of external memory (RAM, Flash) that can be added to a system using a nRF51822. In that case which...
Although there are some posts dealing with bond manager issues, I have not been able to find a similar issue. I am using part of the BLE code from nRFready Desktop 2 v1.0...
