Is there an AT command to change the carrier sense time?

If you have any information, I would like to know.

Thank you.

AS923 of RAK811, “carrier sense” to meet the following standards.

The “ARIB STD-T108 Version 1.0 920 MHz band - Telemeter, Telecontrol and Data Transmission Radio Equipment” specification says something like the following:

Carrier sense
A carrier sense procedure shall be performed before transmitting on a radio channel. It shall be able to determine the presence of RF power on the radio channel (one or more) at a level of at least -80 dBm.
In that case, the channel is considered occupied and shall not be used for transmission.
The analysis duration shall be at least 5 ms for the channels 24 to 38.

Thank you.

Hi leopold,

I sent this email but it may not have arrived, so I will write this here.

In order to use RAK811 for general use in Japan, it is necessary to conform to the following standards.

Association of Radio Industries and Businesses
https://www.arib.or.jp/english/index.html

In Japan, it is necessary to control the following sections.
ARIB STD-T108

3.4.1 Transmission time control equipment
3.4.2 Carrier sense

From these things, I asked if I could set a career sense time.

Thank you.
