After Flashing ESP32, No "Tasmota_XXXX" SSID...How To Connect?

[TSJim]

Hey, I need a little help figuring out what I'm doing wrong.

Tonight I flashed the "tasmota32.bin" file to a Wemos LOLIN32 dev board. Everything seemed to work right, and I got the "Hash of data verified" message. Then rebooted it.

I expected to see an SSID like "Tasmota-XXXX" on WiFi, similar to what happens when you flash Tasmota to a Tuya switch or plug, that I would then connect to and use the WiFiManager functionality to put it on my WiFi network, but I'm not seeing anything.

Is there a different way that I need to connect to a newly Tasmota flashed ESP32?

Hi @TSJim
Happy new year

Did you also flashed the 3 other bins (bootloader, partitions, and the 3rd I can't remember)?
All 3 files are mandatory beside the tasmota app itself.
Please refer to the docs and files in Tasmota/tools/Esptool/ESP32/

Cheers

Hey Barbudor...

Yep, that was the problem.

Here is the command line that worked for me (after booting the ESP32 dev board with GPIO0 grounded):

sudo esptool.py --port /dev/cu.SLAB_USBtoUART write_flash 0x1000 /Users/jim/Downloads/BootLoader.bin 0x8000 /Users/jim/Downloads/Partition_Table.bin 0x10000 /Users/jim/Downloads/tasmota32.bin 0x225000 /Users/jim/Downloads/SPIFFS.bin

I was able to write the files successfully and get the ESP32 connected to Home Assistant!

Thank you.

Are you using the files provided by Tasmota ?
The names are different
The command line is also different from what is provided in the Tasmota doc or the README

esptool.py --chip esp32 --port COM5 --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dout --flash_freq 40m --flash_size detect 0x1000 bootloader_dout_40m.bin 0x8000 partitions.bin 0xe000 boot_app0.bin 0x10000 tasmota32.bin
