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...
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...
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...
I am read the datasheet of vl53l1x ,can anybody help on connection of vl53l1x to nrf52832 and how to use sensor vl53l1x ....any driver code for vl53l1x sensor
I want driver...
I have the following trivial program which has almost identical functionality to the connectivity/ble_connectivity/pca10040e example:

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,
