How to bond between a smartphone and an NRF5 unit for a single secure data link?

[MikeLemon]

Hello everyone,

I'm attempting to "Bond" between a smartphone device and a NRF5 module to have a continues reliable and secure (with password before pairing) data link using the[url=https://github.com/sandeepmistry/arduino-BLEPeripheral]sandeepmistry repo[/url] and the arduino IDE.

Any Idea if possible or how to to that?

Thanks for helping.

Have you tried to ask on the github repo ? We are not people who handling the Arduino library. 

You are looking for bonding with static passkey. I don't know if the Arduino library support it or not. We do have that supported in our SDK. 

This case you can have a look, it mentioned a little bit about requireSecurity() method you can use.

Also great to know that this is even possible! 

Do you maybe have some example for using that with compileable code? Something thatutilizes the UARt intrrface to send and receive data between the units just to get started

As I mentioned, we don't make the Arduino library. Suggest to try our SDK. 

[MikeLemon]

Yes I meant for the SDK. I'm always trying to adopt it but it just doesn't seem to have enough study material, tutorial and support around the internet(or google and youtube specifically) So for the basic hardware settings I use arduino believe I'll have to go with the SDK and SES fully at some moment hopefully I'll be easier until then.

Yes, please try. We have an UART example in \examples\ble_peripheral\ble_app_uart so that you can forward data from UART wirelessly via BLE to the peer device.

Hi well sorry for not touching it up until now, I don't have much time to deal with it sins I'm serving at the military now.

But I've played a little with it now and I've connected an FTDI adapter to the pin 8 and 6 of the nrf5 DK and I indeed receive the messages I send from my smart phone after using the nrf connect app but I don't know where do I see the data I send from the "RealTerm" program through the DK on my phone...

Also I can't find any good walkthroughs for that nrf platform and I'm in a need to make some products based on this MCU is there someway that you could maybe help or direct me to to learn about programming the thing and other stuff? I don't mind even paying per hour for one of your engineers to sit with me online and teach the basics.

Thanks.

Hi Mike,

 

We don't provide such service. But we are trying our best to give you good documentation to use our chip. 

How did you send your data from smartphone to your nRF5 DK ? We suggest to use nRFToolbox to do so. 

To send data from RealTerm, you would need a LineFeed (LF or "\n") character to end a line to be send. If you go to Send tab in Realterm and click the check box +LF in EOL then click Send ASCII what you type in the text box will be sent. You can see your text in in the log of the UART app in nRFToolbox (swipe left to see the log)

To get started I would suggest you to follow what we have in the Getting Started section in Info center.
