The current version (v3.9.2) of (windows) flash download tool has taken several steps in a good direction for 'ease of use' in our production environment, but there are several annoyances that could be easily addressed: - On starting the tool, the user is _still_ presented with a dialog box to choos...

Thanks for the pointer @burtrum. I updated to esp-idf v4.4 (I was on v4.3, which does not provide the example you cite), and checked the multi_config example. It's not ideal, in that it builds the _entire_ SDK twice (once each for 'build_prod1', and 'build_prod2' folders). Of course, apart from the ...

I have an App that builds (against ESP-IDF) for a board used in one product. I need to build the same App for the same board to be used in a different product. The second build requires a subset of the code (i.e., some of the files are not included) used in the original product, plus some 'variation...

Have you seen this issue ? This will only apply if you are running git-master esp-idf. I'd also suggest you slap an oscilloscope on the signals & check for clean transistions on the clock & data. You might need to adjust the pullups if these signals are noisy. Reducing the clock speed can also help ...

Thanks for the link to your android bug - I've tagged it. My comments weren't intended as any kind of solution - only a test you could run to possibly provide more insight into WHAT is going on. I've found other Android vendors (Samsung especially) all seem to introduce their own bugs/features/behav...

From the diagram you linked, only Rx & Tx are connected (RTS & CTS are not used).
Are you toggling the PWKEY signal?

From the manual:

PWRKEY should be pulled low at least 1 second and then released to power on/down the module.

Unfortunately, Pixel does not reconnect to this AP again and choses another network. I'd suggest you re-run this test, but 'forget' all other networks. This will give android no 'other' option, and will increase the likelihood it will follow the AP when it changes channels. I work with a system tha...

You appear to be using Neil Kolban's ESP32-snippets (you should at least mention this - it's NOT plain esp-idf code). There is a BLE multi-connect example that might help give you some ideas: look in './esp-idf/examples/bluetooth/bluedroid/ble/gattc_multi_connect/main/gattc_multi_connect.c', and loo...

Consider that a BLE scan involves the scanner hopping between the three 'broadcast channels', dwelling on each channel to listen for broadcasts. What you would need to do is either 'pause' or 'stop' this process, so you can make the radio link to a single device & read data. I'd suggest you abort th...

I am using a WIFI OTA bootloader to update my application code. My application code stores configuration & calibration information, in the NVS ('NON VOLATILE' Storage). WIFI requires NVS (not sure why, I think I saw something about storing PHY calibration), so the bootloader needs to initialize the ...
