7.5 Network Formation and Join
7.5.1 AT+ASCAN or AT+AS
Description
Perform a scanning for existing network. It can take up to 5 seconds. (CAUTION:
It is possible to cause a link error if a node is a parent of an end-device.)
Execute AT+ASCAN<CR> AT+ASCAN=<channel mask><CR>

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.)

7.5.3 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.)
