B4R Question mqtt is it have similar "wait for" function?

[tzfpg]

I'm using esp8266 and use MQTT communicate with server, any solution make "wait for" available for B4R?

my esp8266 send topic to server and wait receive the data from server and continue in the same sub.

is it can do that?

It is not possible. The B4R framework is too minimal for such feature, as it runs on devices with 1k ram.
