Re: I2C example wanted
This feels like a very low level interface to I2C. Are there plans for high level interfaces to I2C and SPI in the future?

Re: Problems linking with math library - undefined "__fpclassifyd"
Thank you guys. Git hub issue #33 raised. Later ... The problem was resolved and it was discovered to be a mistake on my part in my linking step. I had failed to include my source compiled object files in the --start-group / --end-group recursive linking definition. Once I moved my code to be within...

Re: Can WiFi, BLE and BT be used in parallel with a host MCU
The ESP32 has just been released and the software that executes upon it is still in flux. I understand that it is planned to eventually support WiFi and BLE simultaneously but at the moment, it is one or the other. Don't know anything about apple certified other than to say that it is a WiFi module ...

[Solved] Problems linking with math library - undefined "__fpclassifyd"
I have some code that is including "math.h" from components/newlib/include/math.h In that header there is an external reference to: extern int __fpclassifyd (double x); when I link my application, I am getting an error stating: jswrap_functions.c:(.text.jswrap_parseInt+0x27): undefined reference to ...

Re: IDF refresh process
In my environment, I use a Makefile to build my environment. When I wish to refresh my ESP-IDF, I run "make environment". Here is the Makefile I like to use. I'm not saying that this is a recommended way or the best way and am very open to alternatives. # Makefile for building a local ESP32 build en...

Re: Changing serial port speed causes full recompile?
As a data point, I switched to using compression last night and it worked just fine for me. Some thoughts ... The ESP-IDF is a moving platform. It is being worked upon continuously which means that one should really be downloading/refreshing the whole ESP-IDF project on a regular basis. If something...

Re: Any recipes for over the air flashing/program loading?
I tried 230400 baud and as you suggested, it seemed to work. I did notice a new quirk which is probably how I am working or using the device. Realize that I might be making horrible mistakes here ... I have an application running which is effectively a serial console. This is running on my Raspberry...

Re: Any recipes for over the air flashing/program loading?
Thank you as always sir. Your posts are gold. I wasn't sure what you meant by compression so did some digging. I'm not 100% sure I got it all but here is the story in case others may find it useful. When we extract the ESP-IDF template for a project, we can run "make menuconfig" which opens up a men...

[Answered] Any recipes for over the air flashing/program loading?
My current experimentation workflow is: Edit Compile Flash Run ... repeat While this works great, the "Flash" step takes time. While more than acceptable, I believe I have the opportunity to flash new code into an ESP32 through WiFi (i.e. Over The Air - OTA). Is this area functional at this time? Do...

[Answered] What is the purpose of the "tcpip_adapter" component ...
Within the ESP-IDF there is an interesting component called "tcpip_adapter". I haven't found any documentation on it.
https://github.com/espressif/esp-idf/tr ... ip_adapter
Does anyone know any more about it? What is its purpose, status, usage pattern, stability etc?
