Hi hung, Thanks for the reply. I realised that I can set a public address for all the devices and (as they will only be connected one at a time), I can configure them as they will be automatically paired. Thanks again, Lodge.

Hi Lodge,

If you only have one device running at a time, then it's fine with BLE spec. I assume that you only use that single address for configuration only.

But if all of them can be configured the same way you can think of just simply copy the flash after you configured one device and flash to all other devices.

I'm not sure what kind of configuration you will have, if it's not the same for all devices, can it be done directly via flash writing ?

Hi Hung, If this is the case, could I use the same device ID or does this go against BLE principles? It takes at least a minute to pair using the windows UI, which is going to be a massive pain for every board we need to configure (I will also have to use the UI to remove the last paired device). Thanks, Lodge.

Hi Lodge,

You are right. I didn't know that :) But you still can avoid bonding by rejecting bonding when asked. This may possibly save you some time.

Hi Hung, Thanks for the reply. Are you sure this is the case. Everything I have read says you need to pair with the device first. Such as- https://social.msdn.microsoft.com/Forums/windowsdesktop/en-US/2f236b71-a6ac-4c42-aef3-723c3691cbf8/how-to-discover-connectdisconnect-and-reconnect-to-bluetooth-low-energy-device-from-windows-81?forum=wdk Can this be done with the windows ble api? Much appreciated, Lodge

Hi Lodge,

You can simply make an application on the Windows machine and use that app to automatically connect to the device that has a specific name, or has a specific service UUID in the advertising packet. In this case you don't use the Windows UI to connect.
