Re: WiFi meshed network - how to join strongest AP in STA mode?

The only way I have found to ensure connecting to the strongest AP is to perform a site scan and then connect to the strongest using BSSID instead of SSID.

Re: ESP32 EN pin pulled down

Do you have your power enable tied to your ESP enable, by chance? I had a problem where I had power enable and ESP enable tied together. When the ESP is not powered fully, it will sink current on EN (and other signals). In my case, when I would turn on EN, as power started to come up the ESP would p...

Re: Button clicked, NEGEDGE interrupt fired multiple times

The first post mentioned pressing and releasing a button. Then we suddenly start talking about a rotary encoder. No wonder the solution is different! Susan But ... this doesn't work with the rotary button. The 2 signals have an interval of 5ms (when rotating fast) and I need to know which is first,...

Re: Button clicked, NEGEDGE interrupt fired multiple times

For a rotary encoder, I recommend using a state machine such as the one described here: http://www.buxtronix.net/2011/10/rotary ... perly.html

It removes the need for debouncing and makes it much more reliable over all.

Re: ESP32 Powered 3D Printed Robot Arm

This is really incredible work, thank you for sharing! I've followed your Github repo and YouTube channel. Really looking forward to seeing your progress on this! I have no experience with robot arms, but I have seen in videos where they are often trained by holding the end effector and moving it ar...

Re: 3.0 -> 3.3: Partition ota_0 invalid: Size 0x1db000 is not aligned to 0x10000

Okay, I was mistaken about the commit. It's actually this one: https://github.com/espressif/esp-idf/commit/57b601ab7f6254e98b29d6f48124055b59f57d15 And this seems to be specific to secure boot, and fixes a security issue, and I see that an option was added to turn it off with a good explanation of w...

3.0 -> 3.3: Partition ota_0 invalid: Size 0x1db000 is not aligned to 0x10000

Hi all, I'm in the process of moving from 3.0 to 3.3 and I'm getting this error when building the partition table. I understand the error, and I've found the commit where the error was added (https://github.com/espressif/esp-idf/commit/7eb0b3c2d776e5b35b3eec1d9f20ece05f6691f1) but this leaves a few ...

Re: Problems enabling secure boot: csum err

Hi WiFive, back at work now and trying this out. How do I change the partition table offset in IDF 3.0? I don't see the option in the menuconfig.

Thanks,
Jason

Re: Problems enabling secure boot: csum err

Thanks WiFive, that looks like it's probably it. I can't test till Monday, but I just ran a full flash command with the bootloader included and it complained about the overlap. Seems like this could be a really simple fix from Espressif's perspective? If secure boot and flash encryption are enabled,...
