Hi,
I am really new to ESP8266 and IoT.
I am wanting to remove the RS232 cable between my computer and an alarm system I have, in the hope to wirelessly connect then via ESP8266 and use the software i’ve written to control the alarm.
I have a Wemos NodeMCU board and a logic converter to reduce my panel’s 5v serial to 3v3
My first question is, can I connect the panel’s TX/RX (via the logic converter) to the ESP8266 TX and RX pins on my NodeMCU straight away?
My next question is, can a TCP server automatically perform the data exchange between the panel and computer?
Any help with this would be great, I thought ESP-Link might have worked, but it just only allows OTA programming which isn’t what I need. I guess I just need to keep reading up as I am so new to this.
Thanks in advanced
