I love to share all, just miss a file upload option at this forum. Can not upload a screenshot, a profile file etc.
Most forums offer this, maybe someone scared to see the reality here
The truth is that I really tested weeks and weeks with AT,API,Brodcats,Unicast S1 S2 S2C S3B , all kind of antenna's from PCB to wire, to dipole, whatever I tried the speed remains low , even between 2 modules with 1 sending data to the other one ( max 20kbps). At the moment it looks S3B gives the best result 20 kbps in XTCU throughput test if no hops just first module to second module.

You recommend me to increase the payload? I can test and change everything, but at the end what I need is to send small strings as fast as possible from main homeautomation unit to several rooms.
Our string is for example $@13/ZZZZZZ/1/C1/DIM/52/3E@$
I hoped I could update the DIM and RGB value at several (5) rooms with a speed of 20 Hz.
This seems not possible although it means the actual useful data is only 28 * 5 / 20 = 2800 Bytes or 2.8 kbps
At the end I even consider to put the main module in the middle to reduce hops although that is difficult , not flexible and means more then 1 network instead of one.
Broadcast is in all tests slower then multiple unicast. We never need to send 1 message to all rooms but often to several rooms.
Forgive me for asking again, but what throughput I can get from module to module if I send strings like $@13/ZZZZZZ/1/C1/DIM/52/3E@$, and what if 1 ,2,3 hops? IS there a way to calculate, estimate?
