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 ...

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 ...

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 ...

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.

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 ...

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.

What is WIFI_MODE_MAX & WIFI_MODE_NULL difference?

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