+## FreeRTOS Tick Rate (Hz)
+
+You might notice that Arduino-esp32's `delay()` function will only work in multiples of 10ms. That is because, by default, esp-idf handles task events 100 times per second.
+To fix that behavior you need to set FreeRTOS tick rate to 1000Hz in `make menuconfig` -> `Component config` -> `FreeRTOS` -> `Tick rate`.
+
 ## Compilation Errors
 
 As commits are made to esp-idf and submodules, the codebases can develop incompatibilities which cause compilation errors.  If you have problems compiling, follow the instructions in [Issue #1142](https://github.com/espressif/arduino-esp32/issues/1142) to roll esp-idf back to a known good version.

+[EddystoneURL frame specification](https://github.com/google/eddystone/blob/master/eddystone-url/README.md)
+
+   Create a BLE server that will send periodic Eddystone URL frames.
+   The design of creating the BLE server is:
+   1. Create a BLE Server
+   2. Create advertising data
+   3. Start advertising.
+   4. wait
+   5. Stop advertising.
+   6. deep sleep
