Arduino iot 33 & AS32-TTL-100

Hello. I would like to connect an Arduino IoT with AS32-TTL-100 but there are no drivers. It works partially with driver for LORA E32 on this page. I really don’t know if this driver can be used or I connected the hw incorrectly. The manual does not describe the use of PullUP & Voltage divider resistors, but it doesn’t matter if they are there or not, it does not work. IoT does not have SoftwareSerial or HardwareSerial I used Serial1. Can anyone advise me how to do this? well thank you

Exit the program:
