PlatformIO compile error

[mbatini]

Hi Pavel, is it my configuration or some versione problem?

I am using latest platformio and espidf framework. Getting this:

src/main/hal.cpp: In function 'void esp_spp_cb(esp_spp_cb_event_t, esp_spp_cb_param_t*)': src/main/hal.cpp:404:32: error: 'ESP_BT_CONNECTABLE' was not declared in this scope esp_bt_gap_set_scan_mode(ESP_BT_CONNECTABLE, ESP_BT_GENERAL_DISCOVERABLE); tia Mauro

It is the ESP-IDF version, at some point they expanded the call, thus either update ESP-IDF or put the old call, the two calls are:

  esp_bt_gap_set_scan_mode(ESP_BT_SCAN_MODE_CONNECTABLE_DISCOVERABLE); // for older ESP-IDF
  esp_bt_gap_set_scan_mode(ESP_BT_CONNECTABLE, ESP_BT_GENERAL_DISCOVERABLE); // for newer ESP-IDF

Thanks for the promptly answer.

Going to compile now

Ok, compile is ok after ESP_BT_SCAN_MODE_CONNECTABLE_DISCOVERABLE was in place.

I've updated espressif32 platform and it compiles still ok

but it does not link:

looks like ctrl.cpp and hal.cpp have linking problems. Do you have any hint?

Possibly BT options in the sdkconfig thus via make menuconfig

Component config -> Bluetooth (enable)

Bluetooth Host (Bluedroid - Dual mode)

Bluedroid options -> Classic Bluetooth -> SPP
