a) Compiled with IDF release/v4.4 commit(9ee3c83) b) AI Thinker(PSRAM 2MB), log shows RF packet send ok c) WANLAN error changed to hex format; Board status refines prints d) TX/RX/SD task increased stack size for overflow issues e) Remove sdkconfig file, which will be generated automatically

Note: sdkconfig will cause interface error issue, which might be root cause IDF compatibility.

I will try this weekend to check all the pending issues: RPI3 & Ubuntu not rendering, using IDF 4.4 and 5 and any other.

Close and prepare seperated PRs.

And there is a new rate API related fix, see Fix rate adjustment bug and update README.md #28

I managed to fix this issue locally by editing the sdkconfig to free as much IRAM and heap, pin some tasks to some cores and general tweaking. From the looks of it (and very brief debugging with the laptop on the couch) it looks like the packets get stuck in the wifi driver and they never get released.

the sdkconfig is committed, let me know if it's ok on your side

Please check IDF4.4.4 sd_enqueue_proc stack issue #31

PS: I can't add comment this morning, really bizarr.......
