Affected Platform/Device: CC26X2R1

 Description   
  • Git \ Installer version:
    • SDK : 5.20.00.43
  • Test-Bed:
    • Power Consumption 
  • Problem occurring %:
    • 100%
  • Application:
    • ble5_simple_mesh_node_frd_eRPC.hex
  • Problem description:
    • According to the Mesh Profile V1.0.1 
    •  
    • We need ability(according to the TransMIC we are using) to send a packet with a size  == 380[B]/376[B] = 3040/3008(Bit)
    • in the power consumption test when Friend node sending messages (Via eRPC Vendor model TITEST using send_generic_ctx_le API) > 1024bit the RC is -97 or the Friend node is stuck after sending the first packet. 
    • "29_06_21-00_58_12.948842~DUT|send_generic_ctx_le: bt_mesh_model_send_data rc=-97 "
  • Steps to reproduce the issue:
    • Flash a Friend Node and a LPN Node ,
    • Make friendship
    • Send message with size = 3008bit
    • DUT Stuck/ RC = -97
