Empty response
Posted: 19 May 2020, 10:04
Hello all,
I'm getting empty responses while contacting the ESP at its assigned IP address from a browser. Ping response is good. Any ideas on how to determine why this happens?
This started just after setting up a new NodoMCU with the ESP147 firmware as per instructions from the OpenTherm Gateway website (http://otgw.tclcode.com/) and the instructions delivered with those products. The ESP now receives a correct IP address (192.168.1.14) from the router and it listens. An IP scanner finds it there with the name I gave it in the settings. When I browse to http://192.168.1.14 however, I get an "empty response".
Further configuration and using the built-in tools is now impossible. I tried reflashing it but that does not restore the initial behaviour of the chip (where it behaves as an access point).
The firmware came with an "esptool.exe" on which I can find no documentation, and which doesn't provide any information itself. I may have missed a pretty obvious connection because documentation generally seems quite extensive, but I really can't piece it together myself. Any pointers on how to use this tool would also be greatly appreciated.
Kind regards,
Wim
