@polldo can you take a look?

Hi @FluffyMarshMallow26 ,

Manufacturer Data is not displayed if services are advertised

This has been fixed by this PR. You need to download the library from github because it has not been released yet.

Based on other information gleaned from the web, perhaps a scanCallback-type event could be used instead. This would allow another 31 bytes of information to be transferred in the advertising window before connecting with a central device.

Scan response is already enabled and used. Also thanks to the same PR, you can now decide whether to put your advertising data (i.e. local name, service uuid, manufacturer data, etc..) in the main advertising packet or in the scan response packet.
Example here.
Moreover, see #133 , functions used for adding advertising data (i,e. setLocalName() etc.) now return a bool value. This value indicates whether the passed parameter has been correctly added to the advertising packet or not. Thus, if you try to insert a parameter that would make the advertising packet exceed the maximum length, that is 31 bytes, you will receive false as a return value.

Based on Polldo's comments, this features has already been implemented and will be eventually be released.

Thank you for responding to this request - closing this request 24 Feb 2021.
