Sending Radio Freqs via BT to ATR-33 using an SD-Link dongle fails after SD Upgrade to V 4.3.0

We used this great feature to send radio frequencies from the SD nav-display to the radio by using a BT connection between the iPad (runs SD) and our radio (ATR-33) using an SD-Link dongle now since almost 2 years. We really appreciate this feature as it reduces head down time by a significant amount.
Now, since about 2 weeks, this isn't working anymore. Touching a frequency in SD, just a short info appears on the screen what station this frequency belongs to. That's it.
A quick check to find the possible reason didn't turn out anything - the hardware connection between radio and dongle is secure, BT on the iPad is ON and the connection within SD and the SD-Link seems to be established, as it appears in the SD Settings/Connectivity/BT-Devices. However, we renewed this connection, but to no avail.
Funny though, that this failure introduced itself after we upgraded to SD Version 4.3.0.

Anybody any ideas?

Good afternoon,
I have the same problem since end of last June with a Funke 833 and a module I have built.
When testing the output of the system, the data flow is correct.
When sending data from SD, the bell rings and the message telling the frequency sent is displayed.
Maybe we have a problem with the configuration of the tablet?

Dan.
