Boot Inestability about espsomfy-rts HOT 8 CLOSED

Just as additional INFO I have tested with ESPSomfy-RTS v1.7.2 and I was not able to reproduce this problem.

from espsomfy-rts.

The ESP32 libraries were bumped to 2.0.14 between those versions. I also use AIMesh and do not see the issue on any of 10 devices but I will take a look at what is different in those versions.

Thanks. Looking forward to test new versions when available. Again thanks for this amazing project.

I would be suspect of that power supply. In some cases the power supply cannot keep up with the spikes that are created when the WiFi radio on the ESP32 is engaged. This causes the ESP32 to panic reset because of a voltage drop on the EN pin. Which looks a lot like the ping pattern above. There were lots of changes to the core ESP32 libraries for the IDF which is why 1.7.2 which is based on v2.0.10 of the ESP32 core works in your testing.

There are lots of posts on many forums about adding a capacitor to the EN pin to smooth this out but there is another thing that I have run into with another user who had weird labeling on their board. If you have a board like this do not use the GPIO11 pin as a ground. It may work but it will be unreliable.

Yes I am using GPIO11 as ground for the antenna . I will leave my producction environment untouched with v1.7.2 (stable for the last 3 days). I ordered a new CC1101. Once it arrives I will do furthers tests.

That while electrically can be used for a ground it should not be used. That pin is connected to SPI and could be browning out when the radio is initialized. You should use an actual ground pin.

@luismalddonado did you get your issues sorted? From what I have read, that labeling of GPIO11 as GND is a screen printing error. While when pulled low it does provide a path to ground but it also cannot handle load.

I just got today a second antena, tested with it without using GPIO11 fro GND and it works. It would be great to change the "Suggested Pins" section for "ESP-WROOM-32/ESP32S Models" indicating this and the close this issue.

Thanks for the support
