I need to use MSG_SMS_GET_STATISTICS_EX_REQ and handle > MSG_SMS_GET_STATISTICS_EX_RES to get answer. Ah. Yeah, depending on the firmware, only one of those options is available. There is a code at the Siano driver that tries to detect it, but it seems that the logic there is not 100% (well, it works with the devices I have, but I don't have much Siano samples). Maybe we could add a different strategy: - test first if MSG_SMS_GET_STATISTICS_EX_RES work. If it doesn't, fall back to MSG_SMS_GET_STATISTICS_REQ. That is likely better than the current logic, that tries to guess what's available based on a firmware version. I'm out this week for a meeting in San Jose. Could you please try to write such patch and submit to the ML? I'll test it after returning back to Brazil. > I still with problems on scan but as i’m without antenna, tomorrow I will try > again. Well, you generally need an external antenna to get ISDB-T broadcast signals on most places, and a good RC6 cabling with low noise TAPs, if you're using a common building antenna. A very high gain internal antenna, placed at the window sometimes work.
