ESP32-S3 BLE Issues

Posted: Wed Dec 27, 2023 3:53 am

Hi,
I got a custom made ESP32-S3 pcb. I tried my sketch wich is running on an ESP32-Wroom 32D Devboard. I can uoload it and got it running via USB with some modifications, but i can not make it advertice ble, even with using nimBLE.
What could be the reason?
Thank you

Most likely interference on the antenna. Can it connect to WiFi? Load up the WiFiScan example and see if you can find an AP, and if the rssi is what you would expect (should be -30-40db if you are right next to the AP).

I do the upload directly via the onboard USB. After uploading and resetting I can not acces the serial communication as I do not have acces to RX/TX pins. After resseting the Arduino IDE does not recognize the board via USB as long as I won´t bring it in download mode by pressing the bootand reset button. I tried some wifi server examples, but it seems like i does not create a wifi signal either.
