Divided into different commands according to the action

# Reboot

This command is used to reboot the gateway remotely. The request message sample is as follows:

curl -X POST -d '{"action" : "ReBoot","requestId" : "abc"}' 192.168.22.122:80/set
1

return:

{"code":200,"message":"Action Reboot will be run!","requestId":"abc"}
1

# Heartbeat

This command is used to test whether the gateway is online or not remotely. The request message sample is as follows:

curl -X POST -d '{"action" : "HeartBeat","requestId" : "abc"}' 192.168.22.122:80/set
1

return:

{"code":200,"message":"Action HeartBeat succeed!","requestId":"abc"}
1

The server sends a heartbeat package to the gateway to determine whether the gateway is online, and if the gateway receives the control instruction, it returns the successful message directly. If the gateway is not online, it does not return.

# GetVersion

This command is used to get the current version of the gateway. The request message sample is as follows:

curl -X POST -d '{"action" : "GetVersion","requestId" : "abc"}' 192.168.22.122:80/set
1

return:

{"code":200,"message":"Action GetVersion succeed!","requestId":"abc","currentVersion":"1.0.0"}
1

# GetConfig

This command is used to get the current configuration information of the gateway. The message data field is described in detail as follows:

passive passive (1)or active(0) 1 1. There are two types of advertising packets in BLE tags,including advertising packet and scan response packet. Advertising packets are broadcasted actively by BLE tags, while scan response packets are broadcasted passively by BLE tags after receiving requests from scanner. 2. There are two scanning strategies for the BLE module of the gateway,including active scanning and passive scanning. Active scanning sends requests for scan response packets to the BLE tag, while passive scanning only receives advertising packets and does not send requests for scan response packets. 3. If your BLE tag does not have the scan response packet, you can set this parameter to NO, which can improve the scanning rate of the BLE advertising packets. 0or1
