Dear All,
Can i please ask for advice here regarding software serial ?
Is it something wrong with my cubecell or dont undestand how is that work …
When try simple RX test and start from bound 115200 all good i receiving in Serial Monitor - “Normal Serial init”
When i switch to 9600 and reset heltec , i always receive “⸮⸮⸮⸮⸮⸮⸮⸮⸮” - see screen below.
Doing also TX test but never seen softwareSerial.println(“Aaron is a very handsome guy! hahahaha”); - is he actaully handome , maybe this is a problem ? 
Why i asking, just receivied pcb board where i have AB01-v2 and also SIM7080G Cat-M/NB-IoT HAT on one board, developer told me that it should work - once i will be able set serial communication from heltec to SIM7080G Cat-M/NB-IoT HAT .
Tried several times, but decided to come back a little and undestand with simple RX/TX test.
Using below RX test .

Here is image also how i connecting with my module
Will be verry verry appreciated for some tip.
