2.5.11.e. Maximum Allowed Payload 1204
The purpose of this test is to validate the maximum allowable payload sizes in uplink 1205
transmissions. The test depends on properly functioning LinkADRReq and RXParamSetupReq 1206
MAC command control. The first part validates the maximum uplink payload for each of the five 1207
uplink data rates against both receive windows, testing both positive and negative scenarios. 1208
The second part validates the maximum downlink payload for the various RX1DR offsets as well 1209
as various RX2 data rates. 1210
The TCL commands the DUT with some combination of the following settings and validates the 1211
device successfully implements them before proceeding to test max payload handling: 1212
• RX1DRoffset = 0 1213
• RX2DataRate = Maximum default Data Rate, refer [2] 1214
The Maximum Payload size for each region is defined in [2]. 1215
