To increase the chances that the examples work out of the box, this change is raising the default deep sleep wakeup delay to 1ms. If GPIO15 is low at startup, ROM code takes less time to execute (because no logging is performed), so more time may be needed to allow flash chip to become ready.

|
|
Configure the number of universally administered (by IEEE) MAC addresses.
|
|
During initialisation, MAC addresses for each network interface are generated or derived from a
|
|
single base MAC address.
|
|
If the number of universal MAC addresses is four, all four interfaces (WiFi station, WiFi softap,
|
|
Bluetooth and Ethernet) receive a universally administered MAC address. These are generated
|
|
sequentially by adding 0, 1, 2 and 3 (respectively) to the final octet of the base MAC address.
|
|
If the number of universal MAC addresses is two, only two interfaces (WiFi station and Bluetooth)
|
|
receive a universally administered MAC address. These are generated sequentially by adding 0
|
|
and 1 (respectively) to the base MAC address. The remaining two interfaces (WiFi softap and Ethernet)
|
|
receive local MAC addresses. These are derived from the universal WiFi station and Bluetooth MAC
|
|
addresses, respectively.
|
|
When using the default (Espressif-assigned) base MAC address, either setting can be used. When using
|

a custom universal MAC address range, the correct setting will depend on the allocation of MAC

addresses in this range (either 2 or 4 per device.)

Most people are used to end their printf strings with a newline. If this

is sent as is to the serial port, most terminal programs will only move the
|

cursor one line down, not also move it to the beginning of the line. This

standard output code automatically add a CR character before a LF.

When the startup code initializes RTC_SLOW_CLK, it can perform
|
|
calibration by comparing the RTC_SLOW_CLK frequency with main XTAL
|
|
frequency. This option sets the number of RTC_SLOW_CLK cycles measured
|

by the calibration routine. Higher numbers increase calibration

precision, which may be important for applications which spend a lot of

time in deep sleep. Lower numbers reduce startup time.

|
|
When ESP32 exits deep sleep, the CPU and the flash chip are powered on
|
|
at the same time. CPU will run deep sleep stub first, and then
|
|
proceed to load code from flash. Some flash chips need sufficient
|
|
time to pass between power on and first read operation. By default,
|
|
without any extra delay, this time is approximately 900us, although
|
|
some flash chip types need more than that.
|
|
|
|
By default extra delay is set to 2000us. When optimizing startup time
|
|
for applications which require it, this value may be reduced.

If you are seeing "flash read err, 1000" message printed to the

For each received packet in static rx buffers, WiFi driver makes a copy

For some applications, the WiFi driver receiving speed is faster than application
