Hi,
I want to dowalod FW via HCI command. I do the steps as "WICED HCI UART Control Protocol".
Below is my test steps, I write the wrong data to ram on purpose. I think this steps should make device cannot run because I have downlaod new FW(though data is wrong) to RAM. But it still run normally with old FW. Below is my steps.
1. 01 03 0C 00--------04 0E 04 01 03 0C 00
2. 01 18 FC 06 00 00 00 C2 01 00-----04 0E 04 01 18 FC 00
3. 01 2E FC 00----04 0E 04 01 2E FC 00
4. 01 4C FC 07 38 7A 21 00 01 02 03----04 0E 04 01 03 0C 00(write wrong data to 0x00217A38 )
5. 01 4E FC 04 FF FF FF FF---04 0E 04 01 4E FC 00
Then device run normally with old FW. Why
