* Fixes BLE data printing
BLE data has no '\0' terminator, therefore it can't be printed as a regular C string.
This fix just prints the BLE data based on its length.
* Simplify printing to a single call
* split menu options + lora_32_V3 fix (#7697)

Wrong name in definitions.
* Fix error in WiFiClient.cpp where the connect function fails for timeouts below 1 second (#7686)
* Update WiFiClient.cpp
This change will allow specifying connect timeouts below 1 second. Without this change, if connect timeouts under 1 second are given, the connect defaults to 0ms and fails.
This will also allow timeouts in fractions of seconds, e.g. 1500ms. Without this change, connect timeouts are truncated to full second increments.
* Make parameter timeout_ms clear
* Change connection timeout_ms name for clarity

* setPins fix ESP32 "specified pins are not supported by this chip." (#7646)
[ESP32: SDMMCFS::begin hardcodes the usage of slot 1, only check if the pins match slot 1 pins.]
setPins() was testing pins D1, D2 and D3 all against D1 ... fine in 1 pin mode when all are -1 not so much if you're trying to get 4 pin mode working.
I now see this function doesn't really do anything on the ESP32...accept now correctly checks that you are trying to use the slot 1 pins.

* Reword "ESP-IDF as Component" (#7812)
I think "Arduino as an ESP-IDF component" or just "As ESP-IDF component" instead of "ESP-IDF as Component" is more correct way to name the link.
1. "ESP-IDF as Component" would imply that ESP-IDF is some sort of library for Arduino, which is (IMO) misleading, because it's true the other way around.
2. It's written as "Arduino as an ESP-IDF component" on the webpage it points to as well.
- Also I removed the capitalization from "Component" as I have not found a reason why is it capitalized.
