Hello
The project I am currently executing will use arduino pro with WL134 to read animal tags and transmit them through LORA. A problem I encountered is that when the MCU is connected to the computer to see the reception of the com port, the performance of WL134 is quite stable, but when I remove the computer. driven by an external power supply of 9V only, the performance of WL134 is very bad. I can't read any tags. I have confirmed that arduino and WL134 share ground with each other.

Solved, it's not a program problem, I changed the onboard capacitor, sorry to bother you
