BLE-link AT commands fail on game controller board but work via USB

My BLE-link does not respond (AT command) when on the game controller board. If I plug in the ble to the usb directly it works.

1. BLE-link module could only respond to AT command when

1.Connected with computer using a USB cable through Serial monitor or inserted on a USB serial adapter (can be ignored since few people would use them together)

2.Using AT command in code.

3.Otherwise, when it was inserted on an Arduino card(e.g.), it won't respond since the TX&RX was connected with USB's TX&RX (only TX-RX could build a serial way, TX-TX doesn't make any sense).

NOTE: All BLE modules made by DFRobot are compatible, so more FAQ could be found in Bluno wiki>FAQ.
