7.5.2

AT+ESCAN or AT+ES

Description

Perform a scanning for energy level of all channels. It can be used to avoid

interference. It can take up to 5 seconds. The RSSI energy level ranges from

approximately -100 to +127 in dBm. (CAUTION: It is possible to cause a link error

if a node is a parent of an end-device.)

AT+DSCAN or AT+DS

Description

Perform a scanning for existing nodes in the current network. A coordinator or

router can have children nodes and they are presented by “CLDn”. It can be

possible to place some conditions such as scan duration, node type and node

name in order. The information of local node is presented by “*”. (CAUTION: A

ProBee-Z*10 with PTv1.2 or earlier cannot receive the response of AT+DSCAN

from any ProBee-Z*10 with PTv1.3 or later. It cannot receive from any ProBee-

Z*20, either. In this case, it is recommended to upgrade PTv1.2 to the latest

version.)

across the last hot of the incoming route. The LQI value ranges from 0 to 255

with the maximum value representing the best possible link quality. The RSSI

value ranges from approximately -100 to +127 with each value representing the

energy level in dBm at the radio’s receiver. The sender of the recent packet and
