Hi...I'm new here.....
I am currently working on a project that required sending data through wireless. So I bought the DIY project module to try it out.
FYI I have modified the code n circuit to send until 255 and displaying it in 2 7-segment LEDs. The modification works out well. The transmission were successful.
However, there are times where it got a lot of noise throughout the transmission. The receiver side keep on receiving random stuffs (e.g. tx 0x00 -> rx 0xff /0xde / 0x00 / 0x11....and so on ).
I have tried stabilizing the voltage input and separating rx module away from crystal yet not helping much.
Now I'm trying to use CRC method to solve the noise issue but I have one doubt. CRC method only check whether the packet received correctly or not, it just cannot confirm the transmission. What if the environment is so bad and my circuit keep on receiving random stuffs, isn't it pointless to use CRC method?
Is there any other way to improve more on the performance?
Thx in advance~~;)
