HC-12 error correction

Good day,
I received the module this morning.
I wrote a simple program just to test the operative range of those modules.
I checked one way transmission only : tx is located in my home basement and the receiver is outside near the entrance gate.
The distance is few meter less than 50 with this set_up.
I used the default setting: 9600 8 n 1 and FU_3 mode. Power supply for the tx is around 3v3 and 4v0 for the receiver.
Two " rubber" antennas is used.
Sine I would like to test the Max communication range, I am asking if is there avaialable a " dedicated " tx pattern of data or text to be used for .
The gap or the repetion rate is interesting too.
The output from my set_up is attached here togethre with the relevant picbasic program used.
Thanks
Ambro

From my point of view is working fine.
You can try out my configs above. Also increasing the VCC of the TX to something like 4,5V will improve the transmission.

I configured the module to operate at 4800 baud.
The max range is now 150 meters with very few errors.
It is OK for my application now.
Thanks
