ESPlorer can't communicate with ESP8266
The first hit on Google for that ESPlorer timeout message is your friend: https://github.com/nodemcu/nodemcu-firmware/issues/784
I think currently your best bet is to build a firmware with "debug = false", ideally from the dev
branch.

I flashed the NodeMCU v0.9.5 to one of my ESP8266 modules. Now I'm trying to send a Lua script to my module using ESPlorer. I already double-checked the wiring.
When I press the "Send to ESP" button, it shows an error:
PORT OPEN 9600 Communication with MCU... ....Got answer! AutoDetect firmware... Can't autodetect firmware, because proper answer not received. ����,�.,�����(�.,�����Waiting answer from ESP - Timeout reached. Command aborted.`
How can I fix this?
Edit: After I flashed NodeMCU 1.4 (master) I get a startup message.
_flash_used_end:402669c3 fs.start:68000,max:14000 mount res: 0 Task task_lua started. SIG_LUA received.

When I try to upload a Lua script I get these error messages.

After flashing a new firmeware without debuging mode, I can upload scripts. I'm trying to build this project: http://www.instructables.com/id/Low-cost-WIFI-temperature-data-logger-based-on-ESP/?ALLSTEPS But there are no data on Thingspeak. The outputs on the serial line seem to be fine. I think, everything should be okay?

Mark over 7 yearsThanks for the answer! Now, I can upload something! But I ran into another issue.

Marcel Stör over 7 yearsGood, then you should upvote and/or accept this answer and ask a separate question for "another issue" ;-)
