Re: ESP32-S3 USB OTG - USB Hub support?

With the Beta USB-Hub support would it be possible to just read the VID/PID + serial from a large number (20 devices total ie. HUBs connected to HUB with multiple devices in each) of connected USB devices (Phones in this case) and detect insertion/removal ? If so I'm very interested in testing this ...

3D step files and gerbers(or drillfile) for ESP32-Ethernet-Kit A v.1.2

We’re developing some test equipment for a customer that requires ethernet and POE. This will only be produced once in a small batch of about 30 units so we’re considering basing it on your ESP32-Ethernet-Kit A v.1.2 to make a fast, easy, and still relatively cheap solution. The problem is just that...

Re: Has the new ESP32-S3 dropped the Ethernet MAC

This is true; it does not have an Ethernet MAC. Note that this is not the only chip we have in development, and while I can't say much more, we're certainly not dropping Ethernet entirely. @ESP_Sprite: A year has gone by since the last post regarding this. So I was just wondering if there is anythi...

BLE Connection stops adverticement on AT-Firmware

Hi. I'm thinking about using an ESP32 module with the AT commands firmware as an ALT beacon that is set up by another "Master" CPU. I've got it working but as soon as I connect with a phone the advertisement stops until I send AT+BLEADVSTART to the ESP32. I could send AT+BLEADVSTART every second or ...

Re: AWS IoT and HTTPS are mutually failed

I finally found the final answer. It was caused by the stack overflow. Which stack? I don't know. But when I reduced the size of each my stacks, it worked. I used stack high water mark to check some stacks, including the system stacks, I could reach out but found none. Anyway, it works now. Samson ...

Re: BUG: ESP32 dev board and reading sd card's (high power consumption + ESP32 hangs)

Could it be that the esp8266 powers up the SD card on init while the ESP32 powers it up on first access? The 18mA extra draw after using the SD card is probably from it being powered. If you want to stop that I would assume that you need to power down the SD card and then do a re-init the next time ...

Re: Wifi / Bluetooth Problems with custom Board

Just guessing but can it be a power supply issue?
Takes a lot more power to connect to an AP than to just scan for them.
Are you sure you can supply enough power to the ESP? Do you have sufficient decoupling next to the power pins?
Good luck

Re: ESP_LOGD crashes when a %s parameter is NULL

The following code snipplet results in a program crash: char *string = NULL; ESP_LOGD( TAG, "*** crash here %s", string ); Since the ESP_LOG * functions are often used for debugging, it is more than annoying when these functions themselves crash, because the parameters are not well defined. I would...
