How do I receive multiple signals simultaneously at a single receiver (433MHz) with multiple transmitters ?
I am working on a polling system. This one is similar to the audience...
Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
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'm using the nrf51822. and then I tested the samples to receive the ANCS and send to iPhone information of temperature sensor.
I would like to merge the two above-mentioned...
According to the nRF51 series reference manual.
10.1.2 Debug interface mode
Debug interface mode is initiated by clocking one clock cycle on SWDCLK with SWDIO=1. Due...
I have the nRF51822 Evaluation kit and put the Heart Rate Demo on the PCA10001 (V2.1.0). When I press Button 0 it doesn't advertise. I have the module (PCA10000) scanning...
Hi,
I was looking at the .map for my project and I noticed that pstorage.c was taking up a bunch of RAM (~600 bytes), which I thought was a lot, so I went into pstrorage_platform...
The document nRF51422_Evaluation_Kit_User_Guide_v2.0.pdf says:

Hi all,
I have a spurious crash in the softdevice I guess.
It occurs sometimes when the master (an HTC-M8 android phone)
rapidly submits characteristic changes

Hi I am completely new to ARM development world. I have been developing for years for PC.
Now I am working on a Project where we have decided to evaluate nRF51822 chip...
I would like to know if it is possible to use the internal RC oscillator without calibrating every 4s with the softdevice disable. I just want to read a sensor every 2s and...
I'm interested in using BT LE to collect data from a number of serial based devices -- a point-to-multipoint configuration. I'm familiar with the UART examples and have seen...
Hi,
i am searching for infos about my concrete BLE-Sig certification situation but i cannot see the forest because of all the trees :o)

Hi,
I know that a lot of question exists on that subject, but I can't manage to have an accurate battery measure on [Nordic Beacon device] (battery CR1632 3V) ( www.nordicsemi...
Using the nRF Beacons app, but cannot see the battery condition of each beacon. Is this already implemented - if so how to turn on? If not how is it implemented?
