ULP GPIO access?

This is running on the devkitc (wroom daughterboard). The files can be put in place of the files in the "ulp-example" project found online and built/flashed. (The files have the same names as the files they replace.) #include "soc/rtc_cntl_reg.h" #include "soc/rtc_io_reg.h" #include "soc/soc_ulp.h" ...

bluetooth classic support in IDF?

I understand BT classic is slated for SDK 3.1. Any news on when we can expect this? Would be nice to have an example that is as easy as wiring up a HC-05 (a very common BT daughter board) for applications running on the APP processor.

ULP access timer peripherals?

I know the ULP can wake after so many cycles of the 150khz RTC after a "halt". Once the ULP is running, is it able to access the timer peripherals? We have a ULP program that reads an optical encoder into RAM so the main processors can then scoop it up. But the loop rate of the ULP is unstable. With...

ULP running at 8mhz?

See ULP code below: This runs at about 80-120khz. Ideally, it loop consistently and at least 100khz. Ideas? This is part of a project to read rotary encoders. Thank you for your time. #include "soc/rtc_cntl_reg.h" #include "soc/rtc_io_reg.h" #include "soc/soc_ulp.h" // Define constants .set rows, 20...

increasing Wi-Fi loop rate

See code below. I am sending small packets as quick as possible. I know I can increase the overall data rate by sending larger packets. But is there a way to increase the packet (loop?) rate itself? I already maxed the CPU at 240mhz. tried different RTOS tick rates, etc. Don't remember if I tried ch...

Re: TCP throughput: How can speed up

I am wondering the same question. Like I am sure many people new to the ESP, you are here for a project or business need and you want to quickly evaluate if the ESP is the part you want or if you should just keep looking. So you run some of the examples and get different results. Iperf makes it look...

Wi-Fi pauses for several seconds after about 150 packets

Searched for this issue here and on google. It appears this is not a problem when using IDF examples but only with the Arduino Wi-Fi examples. I think the reason is the IDF examples can increase the rx/tx buffer size using menuconfig but arduino is unable to use menuconfig. Is there a way to change ...
