Hi,

thanks for posting the log. Unfortunately it looks like the phone has just read the status bytes in the eeprom. From this it decided that there are were no new unsent records. However I can already see that the device uses the normal omron unlocking procedure and command structure.

uuid: 0xb305... -> write 0x0200... (normal unlock procedure)

Data transfer (only checking for new records and then abort):
devrx: 0800000000100018 (start transmission)
 devtx: 18800000001000000094041311020778
 devtx: 5a00ffff954d00e50000000000000000

devrx: 080100026026004d (eeprom read @ 0x0260)
 devtx: 2e8100026026401e802d80008000094d
 devtx: ff09865e094dff09865e08c809191212
 devtx: 2c1b855df835685114e002da00ff0000

devrx: 1601c002860e401e802d800080000100 (eeprom write @ 0x0286)
devrx: ff01860100d6
 devtx: 1681c002860e401e802d800080000100
 devtx: ff018601005600000000000000000000

devrx: 080f000000000007 (end transmission)
 devtx: 088f0000000000870000000000000000

It looks very simmilar to some other devices, so I have made a guess at a driver file.
You can find it in this branch: https://github.com/userx14/omblepy/tree/hem7280t
