Wemos D1 mini PRO / Won't save basic configs in UI

[MrSiO]

Hi.
I have flashed a D1 mini PRO first with 1.8.7 then with 1.9.0-rc.4 but an issue persist.
Wifi config sticks, but all other configs like username, password, hostname, device id, led options etc... all disappear after browser refresh. Able to log-in without password after power off/on.

All MQTT credentials also disappear from the web UI, but it keeps transmitting to broker...

More info:
1.9.0-rc.4 .bin image
used NodeMcu Firmware Programmer
Default configs except set to 16M of flash starting at 0x0000.

Tried flashing with 4Mb setting but flashing won't start.

Thx all for your help.

Huh, didn't know there were 16M flash chips.

This is rough, sorry the upgrade bit you. I upgraded the Arduino SDK version in 1.9.0-rc1. That's my best guess for the source of the issue.

It's still connecting to the broker? That's super weird. What's the output of /settings?

Is there anything interesting in Serial logs?

Hi! Thx for quick reply!
Problem is fixed.

I believe using the BIN file for D1_mini was not a great idea in the first place...
What I did now is install Atom Linux (first time user) and download the 1.9.0-rc.4 source.

I modified the platformio.ini with the following infos:

[env:d1_mini_pro]
platform = ${common.platform}
framework = ${common.framework}
board = d1_mini_pro
upload_speed = 115200
build_flags = ${common.build_flags} -Wl,-Tesp8266.flash.4m1m.ld -D FIRMWARE_VARIANT=nodemcuv2
extra_scripts = ${common.extra_scripts}
lib_deps =
  ${common.lib_deps_builtin}
  ${common.lib_deps_external}
test_ignore = ${common.test_ignore}

Uploaded and now everything is ok!
My added devices are kept in config. So is my hostname and other configs like MQTT.
In the PIN fields, I always had to populate manually... now they are pre-populaed and worked great!

Only issue I faced is when I ask it to REBOOT.. it never came back online...
Had to physically power off/on. No big deal

REQUEST: Could you add a BIN file for the D1_mini_PRO ? They are getting cheaper and WIFI range is way better. Thx alot !!

Glad it's working!

Makes sense to add d1_mini_pro.

For what it's worth, seems like only 4MB of the flash is actually supported with the Arduino SDK: esp8266/Arduino#2581.

Great job releasing the .bin for the D1_mini_pro! Works great!!
