巴基斯坦采购需求：电池管理系统、BMS电池、BMS模块、锂BMS、BMS锂电池、Lifepo4 BMS

I'm working with a daily BMS equipped with a single UART port. Currently, I'm implementing a parallel interface board that also connects through this UART port. Additionally, I'm looking to incorporate a WiFi dongle, which also requires a connection via the same UART port. I'm reaching out for advice on how to effectively connect both the parallel interface board and the WiFi dongle to the BMS without any conflicts. Would you recommend any specific solutions, such as using a multiplexer or a different configuration? Any insights on managing the communication between these devices would be greatly appreciated. Thanks!
