BLE print on UART0 even with no log output option on SDK

[torarqui]

Context: ESP32 with IDF 4.0.2, Bluetooth SPP active, BLE active, no Wifi.

We are seeing a strange log message being printed on UART0 even with no log output config on SDK enabled, and calling esp_log_level_set(*, ESP_LOG_NONE); in code:

Fix no acl resched Problem.sta: 0x3ce02

I found out that this string is present inside libbtdm_app.a at line 943.
Can someone point out from where this message is coming from, an how to prevent it from being output to UART0?

Thanks!

I see same thing sporadically, did you solve your issue ?

Not yet, we are using UART0 to interface with another chip and this prints keep interfering in the communication
