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...
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 have a project which need to use two UART interface at the same time.
As well known, there only have one hardware UART interface in nRF51822/nRF52832. If I want...
Hello, DevZone,
I have programmed an nRF52-DK with the unmodified SDK's ble_app_hrs_pca10040_s132 (heart rate monitor) BLE peripheral application. I also have a Power Profiling...
Hi Susheel,
Thank you for your support.
We would like to get your advice related our new design, with the followings:
Assume we need to support besides of the BT5...
Hi,
I am developing one of the my project on custom board, in which I have to configured the two GPIO Pin's as input to sense the those pin and take actions assigned on...
I'm developing a battery powered BLE sensor application where I need some basic guidance on how to implement this:
The sensor action consists of a measurement process where...
Hi there!
I appreciate your work on Nordic SDKs which are getting better and better.
But sometimes SDK setup isn't as quick as it could be.
E.g. for evaluation purposes...
Hi,
I am trying to port the Thingy project (ble_app_thingy_s132_pca20020) to Segger Embedded Studio on a Mac and it proved to be not an easy task, in fact I have hit a...
Dear all, I am building a BLE thermometer based on nRF51422 chip. I need to get certify it and if any of you performed and have the tests results of the below tests, for the...
The board came pre-programmed for MBED. I don't need that, wood like to enable regular JLink. I believe the process is to get it in boot loader update mode (hold boot/reset...
Hello,
I am new in this platform. Few days ago, my boss give me a nRFgo Motherboard. He want me to write a program that nRF24le1e can read/write data from sensor via I2C...
Just verifying to be 110% sure:
The TRACEDATA1-4 pins may be used as ordinary GPIO pins when no trace-functionality is configured for the debugger? So even if a debugger...
Hi,
I have a PCA10040 connected with some wires to an external I2C device and I need to poll data from the I2C device and send it over BLE, also updating the advertisement...
Hello,
I'm looking at the different way to control / dialogue with nRF9160 module.
I know it is possible to send commands through the UART port or through the cloud, but...
Hello Support,
I have developed one device based on NRF52,it has interfaced 4 sensors.It's working fine.
Now i want add one feature is that if sometime connection lost...
Hi,
I'm doing research on Bluetooth Mesh for which I built a Mesh system for testing throughput. So currently I am sending messages at the max speed (every 25 milliseconds...
