Example

AT+TMCFG=0

Note

1.The coordinator and node should have the same transmission mode before they can access the network.

2. E70 (915NW30S) has no standard transmission mode. Configure AT + TMCFG = 0 or AT + TMCFG = 1, and

their modes are long-distance mode.)

3. After setting the transmission mode, the network information will be cleared

AT+ PIDCFG

Set/Query PANID configuration

restart to take effect

AT+PIDCFG=

Parameter specification:

Acquire the current device’s PANID configuration

Response

PIDCFG:65535

AT+PIDCFG=Value

Parameter specification:

Value:0~65535

Factory default PANID parameter is 65535

Example

AT+PIDCFG=65535

Note

1. The node can only join the same network as its PANID (any network can be added when it is configured as 65535)

2. After setting PANID

the network information will be cleared

10

AT+ DMCFG

Set/Query device sleep time configuration(restart to take effect)

AT+DMCFG=

Parameter specification:
Acquire the current device sleep time configuration
Response

DMCFG:0 or 2~30

AT+DMCFG=Value

Parameter specification:

Value

Sleep time, unit

S

),

Can be set to 0 or 2~30 seconds

Factory default parameter is 6

S

Example

AT+DMCFG=0

Note: When set to 0, the sleep node can never receive data from the coordinator and can only upload data to the
coordinator, but the sleep node cannot automatically determine that it is disconnected from the network, it can only
determine that it is disconnected from the network after ten failed communications.

Factory default parameter is 60

S

Example

AT+RSCFG=60

Note: This parameter can be used for node disconnection detection.
