I want to know if Nordic has upgraded the protection...
Hello,
I'm looking for answers and some explanation for two main questions - is it possible to perform non-simultaneous multi-image FOTA over WiFi? Is it possible to support...
Hi,
I am wanting to talk to this external 1Mbit RAM chip through an SPI interface: https://www.microchip.com/en-us/product/23lc1024 with the nRF5340 device. Preferably,...
Hi
It seems that the default minium DTLS handshake timeout is about 1 second. That means, there is a retransmission if a response isn't received within this timeout. In...
Hello,
We are developing nRF5340 SoC and is currently using Thingy53 as our reference design, our NCS version is v3.0.2.
So far, we've been able to use dfu-util tool to...
Hi,
Due to pcb constrain, we need to use single button mode with PG/RESET routed to SHPHLD. In this mode long press for reset in the datasheet but nothing is said about...
Hi,
I am curious what is the main difference between nRF8001 and nRF8002.One is for connectivity and the other is for proximity. However, I would like to develop an application...
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. */

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...
