Note 1: Different module sets for different powers. You can check the transmitting power in manual 6.2.

6.3 Notes for serial port upgrade firmware

If the customer needs to upgrade the firmware, it needs to find the corresponding BIN file provided by the

official, and then use the official provided upper machine to upgrade the firmware. Generally, the user does not
need to upgrade the firmware, so do not use the "AT + IAP" command.

The first necessary pins for the upgrade must be introduced (M1, M0, AUX, TXD, RXD, VCC, GND), and

then send "AT + IAP" command into the upgrade mode. If you need to exit the IAP upgrade mode, you need to stay
on and wait for 60 seconds, the program will automatically exit, otherwise even if the restart, it will enter the
upgrade mode indefinitely.

After entering the upgrade mode, the port rate will automatically switch to 115200 until you automatically exit,

with a log output.

7. Use of the relay network mode

Relay mode description

1

After setting the relay mode through the configuration mode, switch to the general mode, and the relay

starts working.

2

In relay mode, ADDH, ADDL is no longer used as the radio address, but corresponds to NETID forwarding

pair. If one of the networks is received, it is forwarded to another network. The repeater's own network ID is

invalid.

3

In relay mode, the relay radio cannot send and receive data and cannot perform low-power operation.

4

The user enters another mode from mode 3 (sleep mode), or during the reset process, the station will reset

the user parameters, during which the AUX outputs a low level.

Description of the relay networking rules:

1

Forward rules, the relay can forward data between two NETIDs.

2

In relay mode, ADDH \ ADDL is no longer paired as a radio address and as a NETID forwarding pair.

as shown in the figure:

Level 1 Relay

"Node 1" NETID is 08.

"Node 2" NETID is 33.
The ADDH \ ADDL for relay 1 was 08,33, respectively.

So the signal sent by node 1 (08) can be forwarded to node 2 (33)
