Bluetooth initialization fails ESP32

[Frank]

Hi,

I’m having a problem with my Bluetooth initialization when I’m combining all the functionality I need. My program needs three things: Bluetooth, MQTT client over tls, HTTPS client.

When I build my program, any combination with two out of three work.

Building with all three components causes the ESP32 to crash during the Bluetooth initialization.

First some errors/warnings:

E (2596) phy_init: load_cal_data_from_nvs_handle: failed to get cal_data(4354)

W (2693) cpu_start: failed to load RF calibration data, falling back to full calibration

Then during the Bluetooth initialization:

BTDM CONTROLLER VERSION: 010101
btip start

I have put the build logs, output logs and some additional information on pastebin. I suspect it is a nvs(flash) issue since the image corrupts after. Might it be overwriting the Bluetooth flash data?

Any ideas on how to fix this?

Hi,

Sorry, we are not the vendor for the ESP32 IDF and hence can only provide help on issues related to VisualGDB. If you can confirm that this problem only happens when using VisualGDB and not when building from the ESP-IDF directly, we will re-investigate it, but otherwise the ESP32 forum is the best place to seek advice on this.

My program exceeded 1M specified in the default partition table, writing a partition csv and generating a binary from that and editing esp32.xml to specify the correct partition table file solved my problems.

Thanks anyway.
