Wi-Fi RTT: We actually have a fair bit of the hardware needed for something like this already; we just haven't had any requests from big customers to write the added driver support for it (at least, that's what I understand); also, I'm not sure if hardware support actually has been tested in any ...

I found that recently crosstool-NG enabled TUI inside gdb and this seems not to play well with Cygwin.

adding to the gdb options lets the toolchain compile finish. Since I'm using Eclipse I figure I won't use TUI anyway.

Just in case others are having the same compile issues

Example I2S projects for the ESP8266 are available.

There is Arduino ESP8266 support for I2S. Play WAV files from SPIFFS: https://github.com/bbx10/SFX-I2S-web-trigger

These are great resources for I2S output, but ...

@davydnorris,
My hope is to try and eventually cover every nook and cranny. Unfortunately, I don't have any additional information on ESP32 than the rest of the community does. We are all waiting and watching keenly for news and updates on ESP-IDF and how to leverage it as best as possible. It is ...

Thanks so much for your book - I bought it a while back and am especially appreciative of the ESP32 updates.

One area I am really hoping will be included at some stage is some stuff on DMA and especially a section on I2S input and output. There's so little out there anywhere on I2S and I'm ...

Done. You may now run:

Shame.

With the CC2650 you change protocols simply by flashing a new stack. I thought it would be as simple as that with the ESP32

No, I thought Bluetooth 4.2 ran over an 802.15.x radio but perhaps I am mistaken.

I've previously been using the TI CC2650 radio chip which supports BLE, Zigbee, and 6loWPAN native on a 802.15.4 radio and I so I thought they were all built on the same physical layer, and it got my hopes up for the ...

One of the least documented interfaces on the ESP8266 is the I2S, so I am really hoping that this will improve the documentation of both chips!

It was only through the work of a few community members that I found out how to do I2S input using DMA buffers - this section of the documentation is ...

Hi Espressif,

Firstly big congratulations on the ESP32 release - I have been very excited to see this chip for a while now.

I was very, VERY interested in your announcement of built in BLE/Bluetooth 4.2 support, because this meant you have built in 802.15.4 radio layer.

Will you also be ...
