I think my earlier posts will just repeat what I said. SPP is an ESP BT example I think. There is not a BLE SPP profile. There are plenty of examples about emulating SPP over BLE however. I seem to remember that I copied an STM32 application guide. This coupled with the ESP examples gave me the mean...

Search for ioctrl.h in the ESP folder. If it does not exists download and add somewhere (but eventually this might cause other issues which you then have to resolve). Next & also if IDF has icotrl.h you need to update your search path. In your 'component.mk' add something like: COMPONENT_ADD_INCLUDE...

'The chip and firmware may be "fine"' Maybe but are not. CAN silicon is especially an issue for me. Have acceptable IDF patches (thank you ESP) on my IDF revision but then ESP refactor between versions with huge changes & my patches no longer works & I do not have a clear/easy route forward. So the...

Well it depends on your bandwidth needs/requirements. BLE/BT would be a good starter using SPP if linking to a phone. Look at this way, how may Phone periperals use Wifi? Why do you think Wifi? If point to point then BLE/BT might be better. Regardless of transport link you need to be clear about lat...

As I read this; it does not work at volume on your board. I did not hear you say that it works at volume on an EVB.
Plz clarify. A simple trueth table would help.
When I read 'custom' its a fair bet to ask OP to post the 'custom' code or schematics. Post your schematics.

10Hz few bytes is not a problem. Thats like 1KB (forget minimum packet size). Go with your original idea IF you have a driver/transport layer which works with the ESP32 IDF. UDP or TCP? Well that depends (again). If you want all the data (only lose data in unacceptable long term hung scenarios) then...

I suspect that a little seeding on your part would be quicker than any one else unraveling your question.
You can fstat a partition and so work out how your config relates to the FS etc.
Or just a whole set of fopens working through the possible paths strings and printing the return code.....

Its not clear what you are asking. I had a quick look at the HX711 reference manual (not the biggest manual!) & there is no mention of calibration parameters or indeed soft configuration. What exactly stops you waking from sleep, wake and reading a value? Perhaps you need to use a GPIO to hold the H...

1 task, like http server task, can run on just 1 core at the same time, so even if you would like to perform parallel reading from sd card/flash to have 2 tasks running, it is not possible, because you just have to know in front what file to process and have data prepared The OP did not mandate the...

I guess it all adds up. I cannot answer for the poster but webpage download speed has been an issue for me. A small/medium webpage might be 2 or 3MB say (just check out the size of bootstrap!). That's 0.24 seconds @100Mbps or 0.5 seconds @50Mbps, 1 second @25Mhz. Actually it would take much longer a...
