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.

Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I'm working on S110 peripherial <-> S120 central project using GATT. I have succesfully implemented S110-based peripherial device with some custom characteristics...
Hey All,
I am trying to create a simple data transfer system using a DFRobot Bluno (CC2540 chip) as the central device, and a Redbear Labs Blend (nRF8001 chip) as the peripheral...
Hello all,
In many thread I can read that it is not recommended to use the internal DC-DC converter to supply the nRF51822.
Can you tell me why it is better to use an...
Greetings all -
We have an nrf51-dongle for development and testing purposes, and are unable to connect to the device over USB with any of the Segger or Nordic tools. I...
Due to BLE's low range, license costs and unneeded complexity, I am looking in to pure radio RF. I am curious about ESB and Gazelle, and which one is good for relatively simple...
Testing OTA using nRF Toolbox on Android. Everything works fine, but for some reason the file selection is "stuck" in dropbox, i.e. I can not go up a level from dropbox, and...
my development environment is nRF-DK and IOT SDK
Q1 : IOT SDK Support Gatt Profile?
Q2 : IoT SDK Support DFU mode?
Q3 : in ipv6 coap server example, how i broadcast...
Hi!
I have custom board with nRF51822 and I need to communicate with serial flash W25X40 using SPI master example with SoftDevice enabled (S110 is used). I worked with...
Hello Everyone
i am using LINK LOSS service i would like to send notifcation to the peer device if the connection is lost and also if the connection is made between two...
Hi,
How to send large amount of data, using multiple characteristics? Assume that my data size 800 bytes and characteristics with notify property. I did splitting the data...
Hello,
I am looking for a way to send more than 20 bytes by using 'sd_ble_gatts_hvx' function.
I want to get the maximum debit that is in theory 6x20 bytes
Do I just...
Hello everyone,
I am doing a project in which a nRF58122 is getting data of an accelerometer and an ADC. Those can be set a really high frequencies. The problem is, when...
Hi all,
I'm working with the Nordic nRF51422 DK that has the nRF51422 chip with 32 KB of RAM.
My application works great on it using the SoftDevice S130 as BLE stack....
