Tool/software:
Hello to all,
I have some questions regarding the SimpleLink CC2662R-Q1 WBMS module, can you please help me on them :
Thank you in advance.
Best regards,
Hi Yossri,
1. CAN is not currently integrated. Could you please describe why CAN is needed? In most cases today, WM is connecting to a Host MCU which may need CAN there.
2. Application layer code is open source in TI WBMS SDK. Customer can implement customized code. Payload size limitation is 230B from MAC layer which is not changeable. Could you please describe why 230B is not enough?
3. TI WBMS network is a bi-reactional communication network. WDs can send sampled data to WM, and WM can send command to WDs in parallel.
4. Not sure where communication latency as 12ms comes. TI WBMS network communication is based on Super Frame. If the requirement comes during current SF bus. Then it is possible miss the SF, and wait for the next SF bus. Is this the latency referring to? If so, the latency is a number that relates to network size. Because larger network will have larger SF. So what is your network size?
5. Please check User Guide in SDK. Power management section.
6. TI WBMS network is based on TI-RTOS which support multi-threads.
7. IDE is CCS and application layer thread is open source that customer can change. Driver interface on TI WBMS solution remains the same vs CC26X2 BLE devices.
Hello thank you for your answer : So have some other questions can you help me on them please:
Does the ASIL-D qualification remain valid when using a CAN booster pack with the WBMS launch pad ECU (i.e., Battery Control Unit – BCU)?
Is direct communication possible between two launch pad ECUs?
Can bi-directional communication be established between two launch pads?
Does the SimpleLink WBMS SDK include the necessary code to interface the booster pack with the BCU?
Our primary interest is in the SoC CC2662R-Q1, which handles wireless data transmission and reception. Since it supports SPI, is it possible to:
Could you provide details on which MCU is used in the BCU, alongside the CC2662R-Q1?
Are there any other available boards that support both CAN communication and wireless connectivity and are ASIL-D qualified (except for the wireless component)? If so, we would like to explore them for our use case.
