MMDVM_POG STM32F105 stop working TX after 175 second #215

Hi,

We have use board MMDVM_POG STM32F105 with MMDVM firmware 20190130 version and lastest MMDVMHost on our repeater. After every 175 second transmission in DMR mode, the MMDVM_POG board is frozen. PTT is ON, COS led is light. Only Power off/on help to works MMDVM_POG again.

In MMDVM.ini the TIMEOUT is value 240 seconds.

If we set the timeout value lower than 175 s for example 160 the timeout works and MMDVM_POG board not frozen and we can start new transmission.

The problem is when we use MMDVM_POG on the repeater (DUPLEX ) mode and local user RF start use But when traffic is incoming from the network the TX works without problem 175 seconds. It looks like a problem in duplex mode when is traffic incoming from RF and TX frozen after 175 seconds

Yes, I have exactly the same problem and just turning off the power and turning on helps until the same time.
