Connecting multiple clients

[djlins]

Hi there,

I’m getting the hang of this now. I have followed the tutorial called:
Using the nRF51 device in a Bluetooth LE Central role
and I have it working fine with 1 device connected through to my nrf51 dongle and it is working brilliantly.
I am sure I saw somewhere that it is possible to connect up to 8 devices to the dongle but I am having trouble finding out how.

I tried a couple of quick things like commenting out the
// sd_ble_gap_scan_stop();

in BLE_GAP_EVT_ADV_REPORT
or letting it run through and starting a new scan up again with:
scan_start();

but that causes issues with the connection of the original 1 device.

Is there a tutorial or any help I can get with how I then carry on registering a second, third and fourth client device?

Thanks in advance,

Lindsay.

Further info is:

When I finish registering a device I then call scan_start() again but my
CENTRAL_LINK_COUNT  is still 1

if I up that to 8 then I get the fatal error where I think I should adjust the RAM settings.

Am I correct in thinking

• CENTRAL_LINK_COUNT is the number of BLE boards
• PERIPHERAL_LINK_COUNT is the number of nrf51 dongles

 

I think I need a tutorial for multiple device connections.

Can anyone point me towards some samples please?

I know a picture paints a thousand words so to illustrate exactly what I am trying to do. It is what nRF Connect is doing in the image here (connecting 2 MIDI BLE devices to 1 nRF51 dongle)

But doing it in VisualGDB

Cheers,

Lindsay.

Hi,

Sorry, this looks like a question about the Nordic SDK capabilities, not about the VisualGDB features. Please try posting a question on the Nordic DevZone – you should be able to get support for Nordic-specific issues there.
