Hi

I'm using a TM2 to send some data on serial cable to a PC, using status polling to trigger the app. The data comes up fine on the PC.

For some reason however, after each time data is sent the SIM seems to "disappear" from the phone's point of view. The phone says "Insert SIM card". After a while the phone seems to have "found" the SIM again until next piece of data is sent. Finally, after quite a few times, the phone freezes completely or the app stops working. Have tried mainly on Nokia 3510i but also Nokia 6600 and SonyEricsson 750i with similar behaviour.

I am guessing that maybe the SIM app takes too long time building & sending the data string, and therefore causes a timeout, so I inserted a couple of MORE TIME commands in the code, but it made no difference.

Does anyone recognise this problem?

Thanks

Could you debug SIM<->Turbo<->ME communication? The "founding" seems to be just pure SIM reset - selfhealing (some vendors use it to avoid own phone freezes).

So I guess something went wrong in your code and ME<->Turbo is down, i.e. turbo is not answering (maybe even not sending null bytes (0x60)) - is dead.

Mmm, will be something in code.

MORE TIME doesn't help, turbo/sim runs only in APDU. How long does this operation take? Phones stand a lot if null bytes are sent, the only issue could be if call was on, then it should be short.

Did some debugging:

    139.229 RESET


What I can see is a couple of MORE TIME commands (they are from my code), and then a long command which appears to be an incorrectly formatted SET UP EVENT LIST command (the tag 'c' would be cell broad cast page)

I don't think it comes from my code (but I suppose it does somehow..) - seen anything like it before?

(I'm not using stk_cmd() in the code)

Thanks

Yes, that's trash.

No, haven't. My guess is that something goes wrong elsewhere and calling set_up_event() is just coincidence.
