ESP32 Forum

I'd like to ask a question about the gRPC support mentioned in the recent esp-va Dialogflow announcement (great news BTW!).

I'm very interested in gRPC support on the ESP32 (I hope this means gRPC direct usage w/HTTP2, and not the gRPC transcoding -> REST API). I thought it was not possible to run the gRPC core on ESP32, but it would make so many things simpler (maybe replacing something like MQTT in some cases).

Anyway, my question is more about the gRPC support, and how we could access other APIs (our own gRPC endpoints, but also other generators for different GoogleAPIs). Maybe you could explain a bit how you did that?

Hi,

Thanks for showing interest in Dialogflow. We have indeed implemented the real gRPC on ESP32 (not its mapping to REST APIs). Let me get back to you about how we can make this available generically.

Hi,
great news on this topic - any updates or examples on the gRPC implementation?

I would also really like a GRPC example if possible!

Me too! Very interested in the gRPC example

Any update for this?

Hi, we are also interested in gRPC for ESP32. Thanks in advance for your support

Hello ESP_Hrishi,

Do you have any further update regarding this as there are few people are also demanding to use it?

Let us know if you have any update regarding this.

hi,
please, i can use gRPC protocol to send data to Visual Studio gRPC server (c#) ??

So it looks like the ESP Voice Assistant SDK uses Google Dialogflow through the gRPC hooks. Is there any way we could get a generic example of using gRPC in the IDF? Or maybe someone out there has some code they'd like to share where they've implemented gRPC on the ESP ?

Hello,

Did you find anything for that?
