Not Initializing #80

Closed Erdcgh closed 4 years ago

Erdcgh commented 4 years ago

My screen is just stuck on "HASP Not Initializing......."

I have installed the HASwitchPlate.ino.d1_mini.bin onto the D1 mini and have it connected up to the HASP PCB.

I have tried to unplug the D1 mini and just power it up alone and see if I could see an Access Point, but I don't see any. If it was possible to do so.

UPDATE: I see that it is already connected to my WIFI. I have logged into its web page, updated the firmware and set up the MQTT broker. I do see MQTT messages being sent by it. But I still just have the "HASP Initializing......." that is being shown on the screen

That strongly suggests that TX from the PCB is not making it to RX on your Nextion. Check your soldering joints and if you have a multimeter you can check continuity to make sure there's a path from D4 on the WeMos to the RX pad (usually the yellow wire) on your Nextion.

Thanks, That did it. The D1 mini actually had a cold solder joint on it.
