PawelBiela3 commented 2 years ago

Hello,

I have strange issue with one command 17.9.1 Set Configuration I'm sending request to White Beet and I have response,that SPI frame is malformed.

Request C0 27 A0 00 00 10 C4 93 00 21 55 DE 02 00 01 01 00 02 00 04 C3 50 D9 C1

Response C0 27 A0 00 00 01 04 B0 C1

General , I see in example for this chapter , also, that Payload size is incorectly set. Here should be 0F not 10. What is going on?? C0 27 A0 00 00 10 (ReqID: 0; Payload: 18 byte) 01 02 03 04 05 06 (EV ID) 02 00 01 (Protocols DIN70121 and ISO15118 supported) 01 00 (Payment method EIM) 01 01 (Energy transfer mode DC extended) C3 50 (Battery capacity of 50,000Wh) 00 C1 Response: C0 27 A0 00 00 01 (Response; ReqID: 0; Payload: 1 byte) 00 (Acknowledgement) 00 C1

When I increased(+1) Payload Size I get ACK :). Strange. My setup , evalboard EV - ISO15118 - SW 1_00_04

Sorry, I found on documentation, that here we have three bytes for battery capacity Type "Exponential". I wrong understood example.
