spspspsp Posted March 22, 2021 Share Posted March 22, 2021 I've been trying to deal with a similar issue--ESP-01 boards seem to be a crapshoot. I have a bunch that are very picky about what FWs they will flash to. I have ordered some ESP-01S boards to see how much of an improvement those bring. 1 Link to comment Share on other sites More sharing options...

Did you tried to update them (e.g. v1.7.4 or v1.6.2)? Link to comment Share on other sites More sharing options...

All attempts (via PlusCart menu) have failed. I have tried many times. But, as noted, the units work *perfectly* Link to comment Share on other sites More sharing options...

spspspsp Posted March 22, 2021 Share Posted March 22, 2021 My ESP-01 units all have AT FW 1.1.0. They work for the most part, except I get random connection drops, and I have to reboot the PlusCart to re-establish it. Having tried to eliminate everything else, I suspect that either the AT revision or ESP module hardware revision is responsible. The WiFi firmware update option doesn't have an effect on my ESP-01 modules either, but I can see one of Espressif's servers being called. Since switching to the ESP-01S worked for Fierodoug, I'm hoping the same will work for me. Link to comment Share on other sites More sharing options...

The PlusCart menu only tries to initiate the FOTA update function of the ESP8266, this was only introduced with version v1.3.x or v1.4.x Edited March 22, 2021 by Al_Nafuur Link to comment Share on other sites More sharing options...

I can get v1.3.0.2 to install. I'll see if that works. Link to comment Share on other sites More sharing options...
spspspsp Posted March 22, 2021 Share Posted March 22, 2021 No, I was mistaken. I can downgrade to SDK v1.3.0 and AT v0.40.0.0 easily. Just gonna wait for the ESP-01S. Link to comment Share on other sites More sharing options...
+Al_Nafuur Posted March 22, 2021 Author Share Posted March 22, 2021 I recommend to flash this firmware version: https://www.espressif.com/sites/default/files/ap/ESP8266_NonOS_AT_Bin_V1.7.4.zip with the nodemcu flasher: https://github.com/nodemcu/nodemcu-flasher before soldering the ESP.

spspspsp Posted March 22, 2021 Share Posted March 22, 2021 I actually got my flashing issue sorted--I found a firmware that supported OTA updates, and now I'm on AT v1.7.4.0 thanks to the WiFi FW update feature. Seems OK in some short tests, but I'll need to play with it more. 1 Link to comment Share on other sites More sharing options...

Capellão Posted September 25, 2022 Share Posted September 25, 2022 If you are going to use the serial usb adapter ch340g, you will need to connect the gpio to the gnd to enable the esp8266 flash function. 1 Link to comment Share on other sites More sharing options...

"Config" settings are: "Advanced" settings: some parts after updating the firmware version, no longer display their version. To fix this problem, I changed the "SPI MODE" setting to "DOUT", and it worked. Link to comment Share on other sites More sharing options...
