Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary?...
Hello,
I am using a nrf5340 dev kit. When I use SPIM the output from the pins gives the correct hex values but the output's amplitude is only around 100-200 mV. I know that...
Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
Hello,
I want to request AGNSS information from nrf cloud services using my nRF9151DK board. As a first step, I flashed the nRF Cloud multi-service application onto my DK...
Hello,
I just received my Thingy:91X which I purchased through DigiKey. I am trying to connect it to hello.nrfcloud but I keep getting the following message: " The fingerprint...

Hi guys,
i tried to find information about the differences in chip revision
nRF51822-QFAA-R7, NRF51822-QFAA-T and nRF51822-QFAA-G0 but i can't find the R7 or T type anywhere...
1.
Are there any other resources than RTC/WDT requiring 32kHz LFCLK, not listed in Table 28 of nRF51422 PS (i.e. Radio)?
2.
ANT stack requires LFCLK +-50ppm, so +-25ppm...
Hello,
I'm getting an exception while starting MasterEmulator Sample Programs. All indicated Dlls were copied along with .exe, windows ver is 7. the same error happens...
Hello all,
I would like to send Acc and gyro data just like health temperature over nRF8001. Which Service can I use? How can I create one?
Thanks for help in advance...
I have BLE Shield V2.0 and i want to change the device name from the iPhone. We can use nRFGO Studio to change the name from GAP Settings but this is only one time change...
When using proprietary radio protocols only (Shockburst/Gazell) are there any difference between nRF514 and nRF518 chips? Do they behave totally equal so they can be used...
I need to send a data package when radio is ON every time
but I try to send data by "sd_ble_gatts_hvx()" I find it can not work,it seems that I can't call this API to send...
Hi
i'm new in dev zone and i have a question
now i work with nRF8001 and i want to design a pcb for it.
I want to reduce the BOM and for this i want to use only the internal...
Hi,

Hi,
I've the need to write a characteristic value of 65 bytes, from my central device (iPhone/iPad) to a nRF51822 peripheral device, so I was looking at this document for...
Hi, sorry if this is a dumb question. I've just ordered some development kits and maybe that will answer the question, but i'm being a bit impatient!
I want to put an nrf51422...
My sensor is off-standard,so I have to use gpio to read and write my sensor.
Gpio IIC will take about 0.5ms to get data.
My app need send data every 7.5ms,it seems that...
Hi all,
In my project ,I use the SPI to communication between nRF51822 and STM32,but I don't know
how does the heart_rate data transmit to BLE stack.
I am confused...
