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...
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...
I add my own codes in nRF51-ble-bcast-mesh-sdk-8-support project,
then I find that if device_flash_init() is compile to this project,

Hi,
I have app + bootloader in one packet. On Android nRF Toolbox both can be updated in one step using Distribution Packet option. Is this possible on iOS?
I know it...
The BLE Central tutorial (S130 based) does not connect to my peripheral. My peripheral connects fine to the Android MCP and the 128-bit service UUID is what I expect.

I use nrfgo studio to program the hex file. but I have only 128kb of flash and the softdevice took 88kb which left less then 50kb. I have a hex file of 70kb
my question is...
hello.
I develope the using the Nrf51822, bootloader and application not using softdevice llbrary.
the procedure is that one mcu send the mrf51822 by uart. and mrf51822...
Now I have generated bootloader.hex used by /DFU/bootloader.
After programming bootloader.hex and s110_nrf51_8.0.0.hex,the device's name changed to DfuTarg.
But when I...

Hi,
I am using nRF51422 with s130 soft device along with SDK v9.0. I am trying to read/write flash memory using pstorage module. I am using BLE nus service for data transfer...
each time I start my program (nrf51 device) I get an error code I save in flash to check it at next restart. I can read error code 0x20
is this a correct error code and what...
Hi,
I try to generate a PWM signal on PCA10040 with the nRF52832. To do that I copied the code from the Product Specification into my application, but nothing comes out....
Hi,
I made my prototype board using the nrf51822 chip. for this prototype i use an on-board connector + external programmer to flash the nrf51822 chip.
that's work...
I am looking ahead to the time when I will graduate from using the nRF52 development board to building a custom device with the SoC. The PCA10036 chip will obviously not be...
Hello,
I am almost finishing developement of a BLE module using nrf51822.
For mass production, I hope I can program Softdevice/Bootloader/Firmware to 10 nrf51822 using...
