Cannot connect to iPhone

[vladkorotnev]

I'm running the sample code with PlatformIO (Arduino framework on nodemcu-32s with espressif32, on a ESP-WROOM-32 devkit), using an iPhone 7 with iOS 13.0.

Trying to debug I have modified the ANCSBLEClient::setup method as follows:

void ANCSBLEClient::setup(const BLEAddress * address) {
    ESP_LOGI(LOG_TAG, "!! Setup Begin !!");
    BLEClient*  pClient  = BLEDevice::createClient();
    BLEDevice::setEncryptionLevel(ESP_BLE_SEC_ENCRYPT);
    BLEDevice::setSecurityCallbacks(new NotificationSecurityCallbacks()); // @todo memory leak?

    BLESecurity *pSecurity = new BLESecurity();
    pSecurity->setAuthenticationMode(ESP_LE_AUTH_REQ_SC_BOND);
    pSecurity->setCapability(ESP_IO_CAP_IO);
    pSecurity->setRespEncryptionKey(ESP_BLE_ENC_KEY_MASK | ESP_BLE_ID_KEY_MASK);
    ESP_LOGI(LOG_TAG, "!! Setup Connect !!");
    // Connect to the remove BLE Server.
    pClient->connect(*address);

    ESP_LOGI(LOG_TAG, "!! Setup Service !!");

However, looking at the logs, the Connect part of the code never returns: log.log

Eventually, usually when leaving Bluetooth settings, the firmware will then crash due to #21.

Does anybody have experience with such a problem? Thanks

Found a temp fix that works:

If using PlatformIO, change your platform line to platform = espressif32@3.5.0. (anything newer than 3.5.0 will fail)

If using Arduino IDE, downgrade the ESP32 board to 1.0.6.

Exact reason is unclear but it works for me.

I want to hug you! Thank you so much for sharing, I just spent hours troubleshooting various issues, roadblock after roadblock. This last one was the board version though, and now my notifications are working. Thanks!
