No rig control with Yaesu FT-991A

[ilyxa]

Rig: Yaesu FT-991A Cable: few different USB-OTG cables, few different USB cables Phone: Samsung A51 / UI5.1 (testing with Samsung S21FE), change UI lang w/ no results Problem: no rig control / no TX Freq not set, no transmission possible. Rig was set to its default values (MENU reset), already tried different speed, port, etc.

WSJT-X working just fine. All permission for app was done.

If I set freq - no changes, but if I then disconnect cable = rig change freq. It seems stuck somewhere somehow in transit (???).

Step to reproduce:

• connect phone
• start FT8CN (automatically or manually)
• make correct port selection
• set Freq (eg start TX) - no changes on rig
• disconnect rig = freq changed momentary after cable disconnection

Any ideas?

1.audio, Need to increase the value of DT GAIN. 2.CAT, set CAT RTS = Off
