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...
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...
I received my nRF51 DK (with nRF51422, PCA 10028) and I could successfully run the S130 demo app thats included with SDK 8.0.0.
The above demo demonstrates for e.g. :

I was upset early this afternoon because I was experiencing issues with buttonless DFU on Android. As is usually the case, I assumed it was my fault.
First, I reverted...
Hi Nordic--
Our custom nRF51822 design has 13 signals routed into the app_buttons module through the GPIO -> GPIOTE->PORT -> nrf_drv_gpiote.c -> app_buttons.c path. For...
Hi,
I have a problem to program an external board with my PCA10028 board. My external board is a Xuntong chip.
( Heart-Rate-Monitor-2-4GHz-SOC-BLE-Module-based-on-nRF51822...
I'm trying to measure absolute minimum power consumption of the chip using the PCA10028. I cut SB 9, and applied a very sensitive current measuring device to P22. I'm running...
Hi all,
I am having ADXL335 Acellarometer board. Here its giving data of X,Y and Z axis directly in analog form.
So how should i configure my IO pins of PCA10001 board...
I've been reading about minimizing the amount of time that the SoftDevice blocks the CPU for, but most of the answers have to do with old revs of the chip and old versions...
We have a peripheral device that we would like to have sleeping 99% of the time. I have a single timer waking it at 1-second intervals to look for things it might need to...
Hi,
I am trying to get date and time on my nrf51822 but struggling a bit. I would like the nrf to receive the time over BLE and then increment it internally using the RTC...
I have a system using the Gazell link layer in which 2 devices stream data to a single host. Each of the devices is assigned a different pipe, and all three (host, and both...
I have successfully set up UART/Serial Port Emulation over BLE example. I have modified it so that it works with two nRF51 DKs, one acting as a central and other acting as...
Hello,
I would like to know whether the below PA can be interfaced with nRF51822?
For our application we need to increase the power of the BT. so I have selected the below...
Hi,
From other forum posts it seems to be very important to follow the reference layouts when designing nrf52 PCBs, but I can only find the reference files in Altium format...
