I create a bin file using the AtPKI.py too and uploaded it to the module using AT+SYSFLASH command. I am using the factory image so the command I used was AT+SYSFLASH=1,"client_cert",0,1040 AT+SYSFLASH=2,"client_key",0,1744 AT+SYSFLASH=2,"client_ca",0,1040 But it seems AT+CIPSSLCCONF=2,0,0 gives NO ...

I am trying to use ESP32/8266 purely in slave mode and I am required to update the certificates on site, It would be helpful if there was a detailed tutorial on this.

Hello, Is it possible to upload SSL certificates to the flash using AT commands? There is AT+SYSFLASH command to view and modify partitions, how do I wirte certificates into the flash using this command safely? A simple AT+SYSFLASH=2,"client_ca",0x00,0x2000 gave me +SYSFLASH:8192,<0xf1><0xf1><0x02><...

I have an ESP32D0WDQ5 (revision 1). I have been reading up on the strapping pins but I cant find a reliable documentation for this part of this chipset. 1) Can I use MTDI pin as an input (Deep sleep Wakeup). 2) If not can I use it as output? 3) Should I consider keeping it pulled up? Any advantage/d...

Hi,
Is it possible to use the input only pins, 34 to 39 as ext1 wake up sources and be able to detect which pin was used to wake up? esp_sleep_get_ext1_wakeup_status(); seem to return 0 for these pins.

Using a percentage is misleading, most people recognize the "bars" for signal strength better than a number. https://www.netspotapp.com/what-is-rssi-level.html It is better to send the strength as collected, and let the server (or consumer) on the other end do the conversion. Raw data is more accur...

I would like to send the WiFi signal strength as percentage via mqtt. What is the conversion factor of RSSI value to percentage?

Please correct me if I am using a wrong method.

WiFi.getMode();

What is WIFI_MODE_MAX & WIFI_MODE_NULL difference?

How do I ascertain what mode WiFi is on: OFF, AP, AP-STA or STA
