Hey guys, I recently purchased this module from aliexpress,https://www.aliexpress.com/item/GSM-GPS-SIM808-Breakout-Board-SIM808-core-board-2-in-1-Quad-band-GSM-GPRS-Module/32435607442.html?spm=2114.01010208.3.2.dDXW4T&ws_ab_test=searchweb201556_8,searchweb201602_3_10057_10056_10065_10037_10055_10054_301_10059_10033_10058_10032_10017_107_10060_10061_10052_414_10062_10053_10050_10051,searchweb201603_9&btsid=c9b2bb9b-a0f1-4ed6-ad2a-85d5957b25fb
It says it uses TTL to communicate. Can I use the Arduino to do that through softwareserial, or do I hook it up directly to the RX/TX pins? I've tried the software serial and that didn't work, and I am not sure what command I need to call for the TTL pins. Thanks in advance.
