E220 using ESP8266

Hello all, i'm trying to use my Ebyte modules but i can't even get the module information. I think it's probably the pinout for my MCU. I'm following the configuration article and based on the schematic of ESP32 I wired up my NodeMCU. But on the sketch, the pins passed to library constructor are confusing me a little.

// ---------- esp32 pins --------------
// LoRa_E220 e220ttl(&Serial2, 15, 21, 19); //  RX AUX M0 M1

Because I put the M0 and M1 on 3.3 V, RX -> TX, TX -> RX and don't connected AUX. Like in the image below: What can I been doing wrong? Thanks in advance.
