Definitely not 121 dBuV into 50 ohms. The datasheet states, in "note 3", that output voltage is presented to a matched antenna (which will have a much higher impedance), and refers you to an application note. I believe this is the application note:

https://cdn.hackaday.io/files/4149177510816/QN8027_SANB_Hardware_Application_Note_V_0_25_102209.pdf

The application note doesn't help too much. Without either the datasheet or app note describing the output impedance of the RF power amp, how are you supposed to calculate power, match to it, etc? I suspect that the -14 dBm you're getting is the truth.

Probably the cheapest solution is to use an NVR with analog inputs.
Some chinese dealers claim to give also an SDK, so you can customize firmware with your own application

NoteI am interested in building my own projects, in PicBasic Pro (this is the only programming language I know)... I made some projects available here : https://dan-projects.blogspot.com/
Thank you in advance if anyone considers my presence on the forum welcome.

Hi All

Regarding ESP32 & ESP8266 latest version do have Jtag support done via OpenOCD a circuit design for the the JTAG interface can be found in Espressif site and can be both for 20~30 USD in aliexpress (not guarantee to work due to fake components use!)
also whether you buy Espressif eval board for ESP32 you will have jtag support using openOCD
the ESP8266 latest version also support Jtag but due to low pin count on the chip you loose some I/O

All the best

Bobi

NoteI design equipment with PIC, dsPIC, PIC32, ARM and other MCUs.
I design the schematic, draw and assemble the boards, write the firmware (basic and application code) and design the case.
The RTOS I use was written by myself.
