Class B Disscussion

[vikasrohal]

Hi,
I'm working on LoRa Class B for our product, but I'm confuse regarding Beacon and Ping
As per My under standing Beacon are used to set time synch at 128sec time interval (Gateway sends Beacons this information to device, Server not involve in this).
Ping are used to send data from Server to Device but for this we need to know Rx window open time at device side, So how this is managed in LoRa mac master firmware

Server - Chipstack LoRa Server

Gateway - GPS (UBlox-7) Enabled LoRa Gateway

Device Log

=========== MLME-Confirm ============ ######

STATUS : Beacon not found

=========== MLME-Request ============ ######

MLME_DEVICE_TIME ######

===================================== ######

STATUS : OK

============ CTXS STORED ============ ######

Size : 24

As per logs device open Beacon window is opened by Ping window not open,
PLease tell me what is actual behavior and what wrong with device firmware
I made changes in device firmware as per discussion no (Class B example- NucleoL073 #1070)
