Bluno not found by IOS app when app in background mode

I have an issue regarding how Bluno (BLEmicro) is discovered via BLE.

While for example the other devices are always found by our app (IOS) when in background mode the Bluno
needs the app to be in the foreground to be found.

Is this a setting that can be changed? I have tested to set AT+MAX_INTERVAL to 40 as is suggested in the wiki.

I am so sorry that we dont have specific information of what needs to be modified. This need to modify a lot of code and we currently don't support yet. I will pass the issue to our team and hope it will have a change before long.

2016-07-09 00:41:03 Thanks Leff, happy to read that it is possible!

Was the first link correct? It's a general search IOS & BLE returning 300+ repositories. Do you have any possiblity to get more specific information of what needs to be modified in order for it to work?

2016-07-06 20:02:48 Got a very quick answer that it can be done by modifying the BlunoBasicDemo.. but it requires knowlegde about ios/android coding, and they gave a link as a clue: https://github.com/search?utf8=✓&q=iOS+ble

This is our BlunoBasicDemo open source file on Github: https://github.com/DFRobot/BlunoBasicDemo

If you want to customize it, we can offer that service for you.

Thank you for confirmation :D

And I think it is because the APP was not supported background mode... I will pass the issue to our team to see what they would come up with and I will update here.

2016-07-06 00:35:58 If the app is paired with Bluno it keeps it connection in background mode, so that works. So yes, the question is how to find and pair Bluno when in background mode.

The IOS app is (successfully tested with other devices) searching and pairing when in background mode. In short we use iphone's capabilty to search and pair with known devices while in background (searching for a specific device ID).

Being far from an expert in this area, but eager to learn, what am I missing? Why is Bluno not found in this search while other BLE devices are?

2016-07-05 19:32:29 Hi fredrik.kangevall,

May I confirm that are you saying it can be LINK/Connetced by the app when it was run in background? Because it makes no sense that bluno would be found when the app was in background~ :roll:
