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...
With reference to the Thingy:91x reference design, I see that the LNA (SKY65943-11) on the GPS signal path is powered by one of the switching converters from the nPM1300:...
Hi,
I'm using cdc_acm to create two COM ports on a PC -
// USB support
& zephyr_udc0 {
cdc_acm_uart0: cdc_acm_uart0 {
compatible = "zephyr,cdc-acm-uart" ;

Working on an ANT project.
Switched a project from S210 to S310 to add BLE feature.
For the ANT part, there is no source code modification at all.
Sweet.
This is not...
Hi, I'm porting the nRF8001 library to a PIC, and now i'm having trouble with the setup process: After i get the DeviceStartedEvent the uC starts to send setup messages, and...
Hi,
I did some small applications using RFduino, and now I will start developing using Nordic sdk.
I'll list some features of my application:
a hardware with no...
Hello,
I'm checking the sleep current with nRF51822 DK board, and have two questions.
sleep current is 2.35uA.
In the datasheet, there is only typical value as...
Hello,
as the S310 V2 uses 11k (9k static plus 2k stack) out of 16k ram. We are running into seriouse memory shortage. Is there any chance to that the S310 memory demand...
Hi.
I'm doing a project on S120 Softdevice and in "ble_gap.h" file (included from S120 catalog) i have noticed sd_ble_gap_adv_start() command. I tried to use it but i received...
Hello,
I'm trying to do a synchronization of two devices over BLE. I want to be able to open a scan window only for as little time as possible to receive a timed advertising...
Every once and a while a compile will result in dm_init() returning NRF_ERROR_INVALID_ADDR. Looking at device_manager_peripheral.c:dm_init(), it looks like this error is coming...
Has anyone experience of successful TICK_DV calibration for nRF9E5? What order of accuracy should be achievable?
In my application I maintain a software RTC clocked by...
Hi,
I want to periodically send data through nrf8001 so that once the connection is established for a particular service, i can periodically send data . So how to create...
Hi nordics!
I want to using app_data for preserving data.
For that.
First, I change the value DFU_APP_DATA_RESERVED to "0x0400"
Second, I change the memory start...
I have the "old style" nRF6310 board + nrf51422 boards.
I want to test different examples from the latest sdk, and possibly with different softdevices as well.
I appreciate...
Actually we are facing some problems debugging our custom code using breakpoints and/or single stepping.
Searching the forum I found that using the uart seems a possible...
I was doing some range testing using the ack payload feature of nRF24L01 modules, and I noticed that using different packet sizes would affect the number of packets per second...
Hi
I have a MCU with an external sensor connected via SPI sampling data at 1000Hz.
Using the nRF8001 with REQN and RDYN lines is making trouble. The REQN line is pulled...
