Hello
Can you explain wiring ?

Will it support nRF52840?

Hello,

I have adapted the code for my Arduino Nano Every (GPIO pins) and adopted the software except for
byte text = 255; -> uint8_t text = "x"; (it's the same datatype)

In the description was the character x, so I chose this. 255 in ASCII would be "ÿ" (actually the character doesn't matter). The problem is that, After I connected all modules and wanted to test whether really no new devices are found, I found however that my smartphone finds sometimes one then again not (am not so convinced).

Questions:

1. the jammer can only block devices unknown to the smartphone from being visible, already known devices are connected without any problems.

2. is there a code to test if the RF modules work. Have read in some reviews that you already arrived defective. How did you test if the modules work?

Greetings,

Petros

Hey,

another interesting question is about the choosen channel numbers:

80 - not available in the source (https://www.rfwireless-world.com/Terminology/BLE-Advertising-channels-and-Data-channels-list.html)
26 - 2458 MHz
2 - 2408 MHz

For my understanding it's necessary to block the three advertising channels and not specific data channels. The picture in the repo shows the frequencies: 2402 MHz, 2426 MHz and 2480 MHz

So I don't understand the selection should it not be:

37 - 2402 MHz
38 - 2426 MHz
39 - 2480 MHz

Hey,

At the beginning of the code you list Radio, radio, radio3 with PA0 etc.

Where you can set the three frequencies?

Can this break the connection between two linked Bluetooth devices?
Or do you have any ideas about this? Thank you very much.
