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...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
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...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
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.

Hi,
I have a simple question. How should I handle situation, when need to collect data and process them before the computed data are sended via ANT+ profile which runs on...
Hi,
I'm working with the nrf5340 and I'm trying to perform a FOTA upgrade over BLE. After initiating DFU with nrf Connect for Mobile the process crashes right after...
Hello,
I'm working on a HID BLE device and it seems to work good with iOS devices. It fails to pair with Window. I'm adding what I can see with the sniffer. Basically after...

Hello,
I interfaced nRF9160 and SD card using SPI. I started with this sample: ncs/zephyr/samples/subsys/fs/fat_fs.
Now once the files from SD card are read, I want to...
Hi, I've began making a SPI module for programming a PIC16. It only transmits data, so two pins. My questions are: 1. any obvious errors? 2. does the EVENTS_ENDTX occur when...
Hello everyone
I have an question when I used the 52832.
First of all,I configed "nrf_drv_spi_init(&spi, &spi_config, spi_event_handler, NULL);" and the file (nrf_drv_spi...
We are about to use the nRF52832 and are looking at which SofDevice to select for a Central-only implementation. The S122 summary says it targets the nRF52820 and nRF52833...
i m using NRF52840 with sdk 15.2. In that i m testing direct test mode by UART.Now i can do transmit mode.i can check through nrfconnect dtm mode. i cannot check receiver...
Hi,
I tried the following AT settings on the nRF9160 DK board:
AT+CPSMS=1,,,"00111000","00011110"
AT+CFUN=1
After this the modem enters PSM mode and the current is...
Hi,
