DSP coprocessor?

Since the ESP-32 goes to baseband I/Q from 2.4 GHz to process WiFi and Bluetooth as a SDR, it strikes me that one of the DSP coprocessors advertised for the Tensilica Xtensa configurable processor intellectual property must be on the chip. It would be nice to be able to access the DSP. I am porting ...

Re: What would you like to see in The Next Chip?

Your strategy of leveraging as much Open Source as possible is working out great, it would be nice to see more of the low-level code opened up. For example, it looks like you have an SDR of sorts in there to do WiFi and Bluetooth, some of us would like to put it to use in other ways, perhaps as a hi...

Re: Wifi / Bluetooth Problems with custom Board

I'd suggest you start by taking a look with a spectrum analyzer connected to a nearby antenna, just to make sure you have WiFi on the right frequency and at a reasonable amplitude.

Re: esp32 AP DNS server sets a default route, it shouldn't, this breaks my phone

From the source code for components/lwip/apps/dhcpserver.c clearing the interface's gateway field looks like it would work, the result is that it sends 0.0.0.0 as the router in the BOOTP response. I'm not sure when the interface is initialized, so I set it (and the netmask) both in my initialization...

esp32 AP DNS server sets a default route, it shouldn't, this breaks my phone

Hi, Using the latest esp-idf for development, the ESP32 access point's DNS server sends DNS option 3, "router" set to its own IP address, and this sets a gateway route on the client. But the ESP32 doesn't perform any routing. So, this makes my phone stop routing to the global internet through its ce...
