@WiFive I tried running serial UART by using a single wire but was unsuccessful by just changing direction of pin. Are there any examples on this?

Does anyone have anything on this?

Sorry for the misunderstanding on what you were asking. My driver still works around them but I have not tested yet whether I need to work around them or not. I'll let you know when I get a chance to test it.

My driver has remained the same. I have also run it using espressif's driver and it works fine with that too. It seemed that the issues above were caused by some bug with wifi, tls or in the hardware dealing with wifi accessing the flash and tls using hardware acceleration for encryption. It is poss...

I want to be able to send a continuous wave over the WiFi in my application code.
I know there is a binary that is used for FCC testing but I'd really like to be able to do this within my application code.
Could I get some source code or get pointed to some resources for doing this?

Thank you!

I got it working. Sorry to everyone for not posting when I did. WiFive pointed me in the right direction. I had wifi using flash storage by calling esp_wifi_set_storage with WIFI_STORAGE_FLASH as the parameter. Changing that to use WIFI_STORAGE_RAM seemed to fix the issues. I also disabled hardware ...

It may be related to the chip version. It is a revision 0 chip. I haven't looked into what went wrong with that chip revision. Do I need a new chip? No I'm on commit ff6a3b1a11032798565d7b78319444aa81881542. I'll try updating to the latest. I previously ran in single core mode but I couldn't get the...

So I've come back to this after leaving it for some time. I have written my own driver that is eerily similar to the arduino low level i2c driver. It seems that the i2c peripheral itself has some issues: The done bit on an end command never gets set even though the end_detect interrupt fired. A read...

I get a similar problem sometimes but the only tasks that miss feeding the watchdog are idle tasks. Here's the output: Task watchdog got triggered. The following tasks did not feed the watchdog in time: Tasks currently running: CPU 0: IDLE CPU 1: IDLE Aborting. abort() was called at PC 0x400d127b on...

I've had issues with i2c intermittently ever since I started using the i2c driver provided. I follow the i2c example very closely. It seems that the issues happen during transmit. In the code, I get 1 of 3 types of errors. After the error the i2c will not recover until reset. timeout error (263) ret...
