Arduino ESP32 bluetooth to serial converter for Renogy/srne solar controllers with RS232 ports. Tested on Renogy Wanderer 30 only with solarAPP and Renogy BT on android.

Needs an rs232 to 3.3v TTL converter on serial2, and a 3.3v linear regulator for power. Alternatively, you could probably wire it up directly inside the unit to the 3.3v side of the on board rs232 transceiver.

RS232 pinout on controller is TX RX GND GND 12v 12v.

ATAC BT432-A Bluetooth to RS-232, RS-422, or RS-485 Serial Converter

ATAC BT432-A RS-232/RS485/RS422 Serial over Bluetooth 2.1 Converter, 3 dBi Antenna

The ATAC BT432-A is an industrial Bluetooth to serial adapter designed to convert an RS-232 or RS-422/RS-485 serial stream to a short-range wireless connection. The compact module contains a Bluetooth v2.1 core interface, radio electronics, antenna, and management software. It is ideal for surveying equipment, machine-to-machine (M2M) communication, system diagnostics, point-of-sale systems, and remote monitoring. It is often paired with a smartphone to allow it to monitor the console port of a system. The BT423 transmits data up to 100 meters with the standard 2.4 — 2.483 GHz modular antenna. Optional higher gain antennas will allow it to communicate with devices at further distances. ATAC’s Configuration Utility runs on a standard Windows-based computer to set up the unit and read and write data.
