I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
We experienced an issue in production, in which about 40% of boards had excess current consumption by about 75uA. Root cause was found to be the PIN_CNF of a GPIO pin. During...
Is there any way that a BLE event handler installed with NRF_SDH_BLE_OBSERVER, can stop the execution of other (following) observers?
I have various modules using their...
Hi
I am a student and this is my first project working on BLE. Please keep that in mind.
The end goal is to create a fingerprinting system with a Thingy (nRF6936) as...
I have modified the BLE app Blinky example so that the LED is enabled (state 1) on power up. However, this is not being reflected on the BLE side because when I connect with...
Hi, when debugging, I'm encountering this problem where relevant SPI registers (likely status registers) signaled a successful read before the actual data could be pulled...
We're developing a mobile application which will communicate with a satellite antenna over BLE. We will not have access to the antenna for a few months, and therefore we aquired...
I am using the UART to perform serial DFU on nRF52832. I got it to work fine using nRF Connect SDK 1.8.0.
Now, I need to pass some serial data to the APP when not in DFU...
Hi, I have to develop a new nRF5340/Zephyr/MCUBoot-based device that communicates with a Windows application via USB. The Windows application already manages other legacy...
Hello,
I'm trying to implement a set up of the ble device name from the NVMC UICR register.
But when I try to take it from the register and to set it has a name, it doesn...
Hi,
when using the spi peripheral in slave configuration, what can I expect at power consumption level? does the spi peripheral derive its clock from an internal system...
Hello,
I am using nRF52840 DK's P20 SWD to communicate with an external nRF52840 board . My setup works fine with nrfjprog running from command line. To communicate with...
Is there any example code using a QSPI image as the input for the bootloader instead of e.g. BLE? What format does that have to be in to begin with? Currently doing DFU updates...
Hello friends
I am fresher for Nordic semiconductor . I want to interface triaxial accelerometer of 15MHZ frequency with nrf52840 with inbuilt ADC and transmit the data...
Hello,
I will try to use the macro ZB_ZCL_SET_MODIFY_ATTR_VALUE_CB to define a callback when an attribut is written in my device. But the callback I write is never called...
I had a look on APIs to use UART in Zephyr in the link https://docs.zephyrproject.org/latest/reference/peripherals/uart.html#uart-interrupt-api . There are three types: Poll...
