Hi All , nothing improoved since March Update …
The data direction from the BLE Hardware to the Samsung Phone allows now full size MTUs of 180byte !
Bad news is that from the Phone to the BLE Hardware is still reduced data MTU of 20 byte ! And thats absolutly slow !
So dear Samsung development … your bugfix was 50% successfully , now please do the rest 
!
Please tell them that they JUST only have to fix the problem with the data direction from the Samsung Phone to the BLE devices !
Samsung development contacted us and they wanted from us an Bluetooth broadcast spy recording that they can analyse the problem , unfortunatly the BLE data connection breaks up directly when you try to send more then 20bytes MTU size from the Phone to the connected BLE device !!
perhaps anybody else can provide the brodcast data recording ??
also PERHAPS everybody with this PROBLEM should create Service Tickets on mass , hopefully they start mooving to fix the bugs !
