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.

Hi,
I am trying to set up a custom service and I have it all setup and it works properly. The only problem is that it is advertising as a 16bit service. I am moving from...
Take into account an application on the nRF51822 and S110.
I have defined different custom services, so UUID is 128bit long.
When advertising:
Is it advisable to include...
What are the mechanics of using 'uuids_more_available'? Is this list transmitted as a part of advertising data, scan response data, or both? How does the host know that this...
I'm using mbed+nRF51822+BLE_API+softdevice 7.1.0 for BLE peripheral side. I add uart service with the setting BLE_GAP_CONN_SEC_MODE_SET_OPEN which is open link, and set the...
Hello,
I know that this question was here before, but I've read all of the questions and answers and still I don't know what I do wrong.
I'm using 3 PWM channels to...
Hi
While browsing the new files in the SDK 8.0.0 i had a look in the new ble_advertising module. In the start advertising function the pstorage access is checked if it's...
Hi, I'm new to BLE and just started feasibility testing, using RF8001, on a small device with no IO. The device will have a unique code set at factory, and printed on label...
I have the nRF8001 plugged into the shield for the Arduino Uno.
From the Arduino SDK from Nordic, I have downloaded the BLE Hello World program to the Arduino, which should...
I know the SDK lists it for the S110 stack:
http://developer.nordicsemi.com/nRF51_SDK/doc/7.2.0/s110/html/a00066.html#app_dfu_intro_sec
But trying to use it with the...
There is a GitHub example:
https://github.com/NordicSemiconductor/nrf51-dfu-ble-S130
It states that the SDK 6.1 is required. Will it work with the 7.2 SDK using the...
