Could not compile the simplest example

I'm trying to solve the problem for a week.

Two PCs home and office.
Absolutelly identical Arduino IDE, VS and VisualMicro setups.
Latest versions of all components.
Example SerialToSerialBT.ino from 
ialBT

Home PC no problems.
Office PC :
Code
Select All
BluetoothSerial.cpp: In function bool _init_bt(const char*)
Error compiling libraries
Build failed for project 'SerialToSerialBT'

BluetoothSerial.cpp: 140:5: error: 'esp_bt_cod_t' was not declared in this scope
   esp_bt_cod_t cod

BluetoothSerial.cpp: 141:5: error: 'cod' was not declared in this scope
   cod.major = 0b00001

BluetoothSerial.cpp: 144:33: error: 'ESP_BT_INIT_COD' was not declared in this scope
   if (esp_bt_gap_set_cod(cod, ESP_BT_INIT_COD) != ESP_OK) {

BluetoothSerial.cpp: 144:48: error: 'esp_bt_gap_set_cod' was not declared in this scope
   if (esp_bt_gap_set_cod(cod, ESP_BT_INIT_COD) != ESP_OK) {


As I understand, some libs(esp_gap_bt_api.h) does not included for unknown reasons, but all #defines are right.

All other my projects successfuly compiled on office PC.
PlatformIO on the office PC also successively compiled that example.

PS
arduino IDE on the office PC also could not compile the example, but with the error:
xtensa-esp32-elf-g++: error: unrecognized command line option '-mfix-esp32-psram-cache-issue'

You haven't provided a verbose compiler output with build properties but I can only guess that your esp core in board manager is different between the two pcs

If arduino and visual micro both fail then this is the common point.

If you have installed any libraries yourself they will be in document\arduino\libraries (sketchbook\libraries). It's not clear from your report the location of the library that is failing. The verbose output will show this.

If the library is included with the esp core then make sure you do not have an older or conflicting version in sketchbook\libraries
