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...
Hi,
I'm using cdc_acm to create two COM ports on a PC -
// USB support
& zephyr_udc0 {
cdc_acm_uart0: cdc_acm_uart0 {

Hi,
We are having issues with this part bridging on our via-in-pads. We are using 2oz finished outer layer copper.
Do you have any footprint recommendations for 2oz copper...
Hello,
I'm looking for guidance and understanding of how to properly use the KMU and ITS for secure key storage of a key generated on device.
I see that typical ITS use...
I'm trying to get some sound out of a piezo buzzer using the PWM library here:

My buzzer has a resonant frequency of 2,730Hz. The buzzer...
Hi all,
I am looking for some help on where to identify a problem that cropped up recently. I'm relatively new to the softdevice concept, though it seems straightforward...
Hey everyone,
I'm developing an application using the PCA10001 board. After a while my app crashes. I think this is due to un-freed memory regions. When writing similar...
Hi every one,
I work on application that read continuous analog signal with 500 sample/second and send it from nRF51822 board (1) to nRF51822 board (2) and read this value...
The BT SIG has adopted the "Indoor Positioning Service" and in there it says ...
"When a characteristic value is written, the Server may check the validity of the value...
Hi,
I need to send an audio signal through BLE connection of nRF51822 module, this signal need to quantized and sampled at rate of minimum 8000 sample/second by ADC, i...
I would like a working example of a simple application that uses soft_device (either S110 or S120) plus UART debugging.
I have read many posts in this forum about this topic...
Hi folks,
do you supply a BT Test-SW to set a module with your NRF51822 in different test modes like continuous FH etc. or to change the device to low, mid, high channel...
Hi,
I want to establish a peer-to-peer communication network between 2 nRF51422, such that both the nRF51422 can Transmit as well as Receive data. Is it possible to achieve...
hi,
as we know, the device need to being linked in 1.28s if Advertising types is BLE_GAP_ADV_TYPE_ADV_DIRECT_IND ,but my host can't link device in 1.28s,so i want to link...
Hi,
I try to evaluate DFU using serial but found difficulty. Seeking help here.
I use PCA10028. First, i falsh S110, v8.0 into it.
Then, compile SDK8.0.0\examples...
Hi all!
I want to allow only 1 device to bond at a time. If another device bonding, I want to delete the previously bonded one.
I tried to use dm_device_delete_all() in...
Hi all,
I'm trying to get TWI working on the nRF51 DK but it's not working.
I used the twi_hw_master_sd.c file so softdevice use should not be a problem.
When I debug...
