I2S full duplex

Hi everyone, Is there a way to get I2S to work in full duplex mode using DMA and 2 separate buffers, one for read and one for write? I can get it to send data using i2s_write , but I can't get it to simultaneously read with i2s_read the data I send out, like I would expect form a full duplex operati...

Re: Minimizing power consumption while connected to WiFi

I'm on the same boat, I want to be able to minimize power consumption while in SoftAP mode. I'm assuming you are in SoftAP mode as well because you want to listen to commands, and this is why the esp_wifi_set_ps won't work: it only works in station mode. More info on this: http://esp-idf.readthedocs...

softAP clients

Hi guys, I have a quick question, perhaps someone can help me out: is there a way to kick out a client (station) connected to an AP? I'm running a softAP, I periodically refresh the list of connected stations, and at one point, since the maximum number of connections is quite low, I may decide to te...

Re: WROVER and RGB LED

I suppose that would be "V4"?

Re: WROVER and RGB LED

Interesting choices on the V3 schematic.... It comes down to this: can't have the nRTS and nDTR lines from the FT2232 in HiZ (floating) because the transistors Q2/Q9 will get turned on. To prove this, force the lines to be either low or hi by opening the port that communicates to the FTDI chip (not ...

Re: WROVER and RGB LED

The silk screen is white. The solder mask is flat (matte) black.

As far as I can tell, there is no revision number on either top or bottom silk screen or copper, which is too bad, because there should be one, so that we can all start referring to these boards by numbers as opposed to colors.

Re: WROVER and RGB LED

I'm running the WROVER on Windows 10 with VisualGDB and program the ESP32 directly via JTAG (Jlink). I do not have the RTS/CTS jumpers on, so most likely RTS should be free from the FTDI chip (one would hope!), but I can't say the same about DTR though. Again, I'm sure the board we have is on a diff...

Re: WROVER and RGB LED

Hi Guys, I bought two ESP-WROVER-32 boards from Adafruit, and I have exactly the same issues with the RGB Leds as described by Mr. Kolban earlier. A quick look at the board revealed that the ESP-WROVER-KIT_SCH-2.pdf is NOT the proper schematic for the Adafruit WROVER kit. In the case of the RGB LED,...
