I would like to update various changes to the specification, such as SAR transmitter/receiver state. For example, in the line corresponding to the link below, I don't understand why it sends a segmented message for a multicast address a fixed number of times, 4 times. This is causing performance issues with my product. https://github.com/bluez/bluez/blob/master/mesh/net.c#L3335 Most of the mesh/net.c code was last written 4 or 6 years ago and is out of date with Mesh Protocol 1.1. Is there a reason for not applying Mesh Protocol 1.1 or is anyone working on? Regards, Junho Lee
