connexion from module ESP8266-01 is:
ESP Teensy 3.6
vcc vcc
gnd gnd

the command AT display nothing on serial monitor
i have tested to invert TX and RX and is a same
i have tested with external power 3.3v for module ESP8266-01 and is a same.
the module work well without teensy, with adapter usb-> serial using terminal a 115200 bauds.
