We're trying to measure supply current used by the NRF9151 DK but have discovered that the current measurment connector (P22) only includes current supplied to VDD, and that...
Hi,
I'm using the nRF52833 to develop a BLE beacon and built a Bluetooth gateway for my application.
Application Requirements:
The beacon should advertise using...
Hello,
I want to perform some antenna measurements and compare the rf performance of my custom PCB with an nrf9160 SiP with the nrf9160 dk.
To perform some antenna measurements...
Hi I want to build a multi role BLE device.
As a peripheral it shall stream ADC data with arounf 20 kbytes per second.
As Central it shall receive adv_nonconn_ind packets...
Dear Nordic Engineers
I developed a PWM function to drive the RGB LED. Then I found a problem, which is w hen I used a PWM signal of one channel to control the RED light...
I get error provisioning key on nRF54L15 and NCS 3.0.1. I tried using "Erase all" in nRF connect SDK Programmer, but it doesn't help. Please check also the attached log. nrf54l15dk...
Hi,
I am using nRF54L15-DK for Zigbee light_stwitch startup testing. After successfully connecting the development board to the Hub for the first time, I evaluated the time...
HI,EVERYONE,
in the document 'nRF51422_PS_v3.0.pdf' ,Page 167, there is such statement

Hi !
According to application requirement, we need to minimize the RSSI variance of the BLE beacon as small as possible. Our RF team has tried to minimize the 37/38/39...
Hi,
I am trying to bond the nrf51-DK with the android smartphone. I want to display the passkey to the user which would be done using BLE_GAP_IO_DISPLAY_ONLY. After which...
Hi, would there be any drawback in setting TIMER_PPI_CH_START to 11 to maximize the number of free PPI for application. 14->15 should be free to use in timeslot and ppis are...
hi, i am new to embedded system.
I am using SPI interface to collect data from the slave(imu) and transmitted it to nrf52 DK,previously,I just used RTT to show the received...
Hello,
I am truing to store data in the UICR register "customer area" from application code. The procedure is invoked only once when the registers are still empty. The...
Hello all,
In controlling two devices simultaneously from one central controller, I have noticed significant time delays in processing the second call to sd_ble_gattc_write...
Hi.
I am using PCA10028 board an SDK10.0.0.
nRF51's Max flash size is 256KB.
Q1. "s130_nrf51_1.0.0_softdevice.hex" size is 302KB already. How can we make HEX file less...
Hi.
I'm using PCA10028 and SDK10.0.0, S130 v1.0.0.
And "ble_app_hrs_c" example is my reference code.
It works well before i add code for timer as below.
void start_timer...
Hi I am an student who is a poor fledging embedded engineer.
I met an error on using nrfgo studio

Hi,
Using ble-app-uart sdk9 example:
Is there a difference where I initialize uart in main? My code is able to run when I shifted the uart_init() after ble_stack_init...
Hi,
I am trying to figure out which GPIO pins i can use as UART on a nrf52 chip if i put it on a custom PCB (Not DK !!). From the reference manual (page 513, 48.10.7 and...
