Hi.
Can you show more of your code?
To share your code, you can use github gist or pastebin, for example.

Hi Sara,
I did find this  Instructables today that talks about issues with simultaneous Wifi and BLE:
https://www.instructables.com/ESP32C3-BLE-to-WiFi-Bridge-BLE-WiFi-Running-Togeth/
Initially, I was going to write this program for WiFi but I switched to regular Bluetooth after not being able to get the Wifi to compile. Bluetooth Serial works for direct control without the Wifi.
I downloaded this code from Pastebin and copied it out of Notepad, not sure if that’s the way to do it. This is the entire program.
Thank you,
Bill

Hi.
Can you try moving the following lines to the beginning of the setup() (inside the setup() function)? 
//init and get the time
configTime(gmtOffset_sec, daylightOffset_sec, ntpServer);
printLocalTime();

Let me know if this fixes the problem.
Regards,
Sara

Hi Sara,
Yes, it worked. I also had to choose the Huge App option (3MB /  No OTA  /1 MB SPIFFS) to clear the out of memory error. Bluetooth serial control is still working.
I will find out tomorrow morning at 5:30 if my other code changes to run a red to white sequence are working. I am slowly increasing my understanding of the Unix standard structure behind ESP32 time.h core.
I’m using this with the 3d printed hinge lamp from Instructables built with a filament spool. If other people are interested, I will upload my working sketch.
Thank you and Rui for all of the great work you do!
Bill

Thank you.
I’m glad everything is working at the moment.
If you have your project saved on Github, for example, you can share here the link so that other can benefit from it in the future,
Regards,
Sara

I’ll mark this issue as resolved. If you need further help, you just need to open a new question in our forum.
Regards,
Sara
