BLE issue on ESP32C6

[oscalcmen]

Hello , I used ESP32C3 with BLE peripheral_esp and peripheral_csc no issues at all, then I swap for the ESP32C6 but found and error
/home/oscalcmen/zephyrproject/modules/hal/espressif/zephyr/esp32c6/src/bt/esp_bt_adapter.c:954:10: fatal error: mbedtls/aes.h: No such file or directory

@oscalcmen Sorry I missed this one. Fix in #97645

[oscalcmen]

Issue solved, thanks

[sylvioalves]

What was the issue after all?

[oscalcmen]

Hello Sylvio, It compiles correctly but BLE cannot be initialized it gives an error I (138) boot: libc heap size 336 kB.

Hi, can you provide me:

1. Current Zephyr branch revision/sha (have you run west update?)
2. Full log output
3. Any extra conf you added into the sample code

Thanks.

[oscalcmen]

Sylvio, Yes, i did west update, Zephyr SDK version 0.17.4, i did not add any other module to Zephyr besides the blob espressif libs. I'm not so sure how to get the full log. Adding CONFIG_LOG_DEFAULT_LEVEL=4 to the prj.conf, terminal showed the below text at booting. (Is there any guide on how to do it?

Can you please confirm the log was for a ESP32C6?
I do not have issues with ESP32, ESP32S3, and ESP32C3, my issue was only for ESP32C6.

for a reason the zephyr was not installed correctly, i did compile and run on another machine and no issues at all.... i had a very old zephyr installed then i updated and probably i did not do it correctly.
