In the past, I managed to setup a ESP8266 to receive signals from my remote, see also Flamingo sf-501 remote - Compatible devices - OpenMQTTGateway
Yesterday I wanted to use the pre-compiled “nodemcuv2-rf” from the web installer ((Option 1) Upload from the web | OpenMQTTGateway v1.4.0), but I could not get it working with my remote.
After some debugging, It appears that I MUST use GPIO 5 (D1) to receive signals. If I want to use the default GPIO 0 (D3) I do not receive any signal at all…
So my questions:
is this problem specific to my hardware? (Wemos D1 Mini Pro V3.0.0)
Is there a way to use the pre-compiled versions but with other pin layout? Some “afterburn” or “slipstream” of something like that?
If I need to compile the code myself: Is there a way to have the same user experience afterwards? I mean: I can change the GPIO in the code, compile and upload the stuff to my device. But (till now) I had to hardcode my wifi and mqtt settings. However, I want to give this device to my friend and I don’t (want to) know these settings. The temporary webinterface to set wifi and mqtt is great but I did not succeed to only change the GPIO and upload the code. Seems that the webinterface is broken than… Probably I’m doing something wrong, but don’t know what.
We could add the capability to change this through an MQTT command.
You should be able to use the Wifi Portal. What was your issue with it ?
I think I miss something. If I download the source code, make my changes as described Flamingo sf-501 remote and upload it to my device (Visual Studio Code + platformio), than I don’t get a SSID from the device.
Do I have to enable the wifi manager manually somewhere?
You need to comment
ESPWifiManualSetup macro to use the wifimanager portal.
yes, I did. But no SSID comming up. Tested now with 2 smartphones and 2 laptops to search for SSID, but no progress.
Try to erase the flash before uploading, it may have persisted the connection in the flash.
OK, that did the trick.
What I did now:
- flash OOB-binary from web with “erase flash” option
- flash with Visual Studio Code and PlatformIO
this works now, SSID is displaying.
Is there somewhere an option in the code to force a flash before uploading the code? I already tried to use the reset button on the device, but this didn’t work…
You could assign to your environment TRIGGER_GPIO, if you have a free button. A long press to it will erase the credentials in flash.
With PIO, you can use the native erase flash function
I couldn’t find that option in the GUI, but within the powershell terminal in VS Code, I can type
pio run --target erase
which seems to do the trick.
This would be great for newbies as me!
