NEXTION with BI7JTA V3F4 "I can not (yet) check or update modem connected displays"

[DL9AM]

Hello Jonathan

I test longer time with help from Winters with NEXTION Display connected on BI7JTA V3F4 board with Winters MMDVM firmware (G4GLX).
Today i test your latest MMDVM compiled with enabled #define SERIAL_REPEATER in Config.h

I have compiled with standard Config.h, only changed #define STM32F4_NUCLEO_MORPHO_HEADER.

All works good, because NEXTION the same problem.

I write with Winters, there only 2 aviable problem with Modem Port: 1. Layout problem or 2. MMDVM Firmware Modem Port.
The NEXTION Display works with Modem Port in RX very good - so all information on Display.
Because the TX from NEXTION don't work - no detect NEXTION (no read out Display Information and noch TX (Reboot, Shutdown) work ;-(

When i connect the NEXTION Display with USB TTL Adapter, it work finde - so all Information at detect and Reboot/Shutdown work.

Here is NextionDriver problem with Modem Port connected on BI7JTA V3F4 board:

I am also facing the same issue. After running an update the display does not update and the RX Frequency does not show. There are several reports online of people facing the same issue.
