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...
We are creating our own dev board.
What pcb parameters were used for the PCA10004-nRFgo PCB antenna radio module 2.0?
1.6mm?
1oz Cu?
impedance control?
I have not...
Hello,
We want to use the J-Link Needle Adapter for nRF51822
The attached (capture.jpg) is the pinout from the J-Link Needle Adapter datasheet.
the attached (capture2...
Hi,
I have a wired problem with the nrf51422,
I'm loading the code using the J-link into my board or the evaluation board (PCA10007) that I have, the code runs perfect...
Hi all, I met a problem with measuring lithium battery voltage. I used 1Mohm and 250Kohm divided voltage, and used the internal VBG voltage as reference, and used ADC0 as...
I'm using a nRF51844
I'm writing my own ADC reading routines because I can't find any examples, but I know how to code so that's not a problem. I just want to confirm something...
Hi,
does a code example or app-note exists that describes how to configure the SPI peripheral to use an ISR to transmit data to a SPI slave?
Thank you in advance!
Dear
Do you know of a "present" /not present" low cost 2.4 GHz RFID chip for static asset monitoring in WiFi environment. compatible with, and actively associates with 802...
I am trying to hook up nRF8001 to TI MSP430F663x via nRF2740 module.
All inputs seems to be controlled properly.
Once I release the nRF8001 RESET line, RDYN goes low...
Hi,
I have a simple battery powered remote control device with a NRF51822 and using the Gazelle protocol for communication with the host.
To save battery the MCU goes...
The last few weeks I'm working with the nRF51422 and run in to several TWI/I2C issues. All of them I could solve except an issue with a SAA1064 7segment display driver from...
We have a custom board with nFR51422. Of the first 4 prototypes only one works correctly. This indicates that the PCB is ok. One difference is the chip marking. The working...
My test: PCA10000+Master Control Panel(3.4.0.8098) as central role, conninterval=20ms
nRF51822+softdevice(5.0) as peripheral role, conninterval=10ms
