ESP32 Forum

Hello friends. I want to use Esp32-c3 for Bluetooth 5 only. I'm thinking of connecting it to STM32. I'm planning to communicate with At commands.

1. Does it make sense to use ESP32-c3 as Bluetooth only? If not, what else can you suggest?

2. If I communicate with ESP32-c3 to stm only with at commands, does it need external flash memory and Xtal? And please provide a link or a documentation about this if available.

I can't tell if it makes sense or not because I don't know your application, but an ESP32C3 always needs a crystal and flash. Some ESP32C3 chips have the flash built-in, though.

I understand you. Thank you so much
