Hi,
I have been using nRF51822 with my Android app using Android's Bluetooth Low-Energy APIs.
In order to get more details, I am currently working on integrating the Android...
I'm looking at interfacing a typical Wheatstone bridge sensor to the nRF51822 ADC. This particular sensor only requires a mA or two for excitation and the output fits within...
When use the "nRFBeacons" app to update the info on my beacon the following happens:
Go to update tab.
Select "Connect"
Press "SW2" on beacon and see the LED begin flashing...
I am using s110 and nrf51822. I've set up up a long characteristic of 154 bytes.
Sending between 1 and 154 bytes works as expected.
Sending 155 - 160 bytes gets rejected...
Hi,
I tested the nrf beacon application, it allows only the beacons with company identifier 0x0059 (nordic's id). But i need to modify it to support all the device, how...
I use a app_timer_create() function to create a task(200ms once)
when in the task_timeout_handle() ,
I do something more than 200ms,
what will this timer going ?
Hi!
I use nrf51-pwm-library ( github.com/.../) to control brightness of LED RGB light source and it works ok till I don't want to adjust brightness slowly (dimming function...
I have been reviewing the antenna section in the datasheet of the BLE audio SoC nRF5340. The datasheet mentions a single-ended antenna output (on-chip balun). Could you explain...
Hi,
When the firmware is run in debug mode (J-Link connected), the system always works correctly. BLE initializes properly, and all sensors function as expected.
When...
Hello, everyone. I am an undergraduate student majoring in Mechanical Engineering in South Korea.
I am currently working on a research project to develop a PPG sensor using...
Hi,
(I'm assuming that the main() function of an application is actually executed as a thread.) I can't find any clear documentation that describes how a thread can suspend...
Hello team,
I am trying to interface the AT45DB641E flash with the nrf54l15 on a custom board. I am using the SPI00 instance.
Below is the configuration I set in .overlay...
Hi Nordic team,
We are working on a design that includes more than 50 peripheral node devices, each capturing sensor data and sending it to a single central receiver. I...
Hi,
I'd like to know how to tune the internal capacitance from the 32MHz crystal.
Specifically, I refered to section 4.12.1.1 Using internal capacitors in the nRF5340...
I am using the nrf52840 in QFAA package, and the external DMIC example receives audio data through the PDM interface. I noticed that the official documentation mentions support...
Hello,
We have been testing/validating sQSPI on nRF54L15.
We tested the sQSPI on two versions of our nRF54L15DK (0.9.2 and 0.9.3).
We are using this sample app: https...
Hello. I have one question.
When configuring RAM with the nRF5 SDK + SoftDevice, if I get the following error: APP_RAM_START=0x20006000 --------------------------------...
Hi,
I'm trying to program the nRF52840 Dongle (PCA10059, 2.1.1, 2023.26). I modified the Bluetooth: Central UART sample to use USB instead of UART and built it for the dongle...
I need to use one IO port of the nrf52832. This IO can not only detect the ECG signal but also achieve system off wake-up. The ECG signal is a PWM signal with a duty cycle...
I managed to somehow semi-brick an nrf52840. I've all but got the system/project working and wrote some instructions on how to install VSC with the appropriate toolchain and...
We are using the NRFJPROG ver 10.24.2 (JLINK Commander ver 8.92) to connect with our NRF52840 target. It fails to connect, here is the log entries:
