Im using SE tunneling cluster in my project. I want to transfer long DLMS/COSEM frames ~512 bytes using Tunneling Cluster. In JN-UG-3059.PDF wrote that: "...Note that the maximum data size that can be transmitted using eSE_TunnelTransferDataSend()should not exceed the maximum incoming data transfer size of the recipient and should not exceed APDU size - 5 bytes..."
Thats why i decided to increase Template used apduZCL to 512 bytes, but i received a stack overflow error. After that i decided to create long apdu for Tunneling cluster only. Now i have a question? Is this right way? How can i rebuild template ESP/Meter project so it began to work with my own APDU for tunneling cluster?
