Re: Examples with copies of xQueueHandles

Yes, but better option may be to make it global variable.

Re: Dynamic GATT on newly advertised devices

You have to connect to device, then search for services and characteristics before you can read characteristic.

Re: Get BLE UUID for iOS pairing

There is no such thing like default UUID. UUID is set in application.

Re: How to get IP address?

This is wrong use of printf.
IP2STR macro returns string, to use it with printf you have to use %s, not IPSTR.

Re: Issues with custom ANCS Notification library

You just cant use Serial.print this way:

Code: Select all

Serial.print(i + " ");
Try :

Code: Select all

Serial.println(i);
Serial.printf("%d%s\n", i, " ");
Or any similar.

Re: SW_RESET continuous reboot

Did you try to install fresh arduino esp32? There is many reasons you can have this or similar error: rst:0x3 (SW_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) It may be as simple as having some pin pulled up or down on startup, read about bootstrap pins: https://github.com/espressif/esptool/wiki/ESP32-Boo...

Re: CONFIG_IBEACON_MODE

There is not much to say with only those logs. There is no crash, no backtrace etc.
Without code nothing we can do.

Re: simple_ota_example pb with ESP-IDF 4.0

Thats possible. Maybe default size of certificate is the issue. esp32 is accepting 2048 bytes key IIRC, but doesnt accept 4096.
