currently i'm developing FMB010 python server for communication with device, but device doesn't clear data after received data number ack,
communication looks like.
1. device sends imei
2. server responds b'\x01'
3. device sends data (b'000000000000004408010000016c4c..........' - according to spec data number is 01)
4. server sends received data number ( b'000001' )
and then device sends nothing and after timeout, it happens all over again, data is still on flash, what response should i send to device ? or is it as it should be ?
