They require a power supply but do not need DC blocking capacitors.

Two antennas are required as L1 and L5 have different frequencies, and different frequencies require distinct antennas.

In Nordic chip development, there are two development kits available: SDK and NCS. Typically, we provide the SDK, while NCS is a bit more complex and runs the Zephyr operating system. Internationally, NCS is more commonly used and is also referred to as the nRF Connect SDK.

The maximum tested transmission power is achieved through chip's matching network, connected to a spectrum analyzer using a coaxial cable. This is known as conducted testing.

Production RF testing, on the other hand, involves connecting the module to a spectrum analyzer using a coaxial cable to measure the conducted power. This is done by contacting the test probes with the ANT pins.

In an office environment, the measured AT Wi-Fi connection time is 5 seconds.

 However, in practical usage, Wi-Fi connection time depends on various factors, including router performance, network conditions, module antenna performance, and more.

You can set it by invoking the AT+BLESCANRSPDATA command.
