I have a device with a strange behavior (Fastrack Xtend FXT009).
The embedded software performs tracking, GPS positions are sent to a server via GPRS / TCP connection.
The exact configuration is:
- Developer Studio 2.1.0
- Firmware R18.104.22.168008311212
- Embedded Open AT Software Suite package 22.214.171.124009161320
- Open AT OS Package 126.96.36.199007281407
- WIP Plug-in Package 188.8.131.52007290812
- C-OPUS-I-GPS Open AT Plug-in Package 184.108.40.2060
The fastrack is powered on a 12V battery. I did the test with several cables for power and the problem appears in all cases.
At first, everything is OK for some minutes. Then there are many reboots during some minutes. Then, everything is OK, then reboots…
I log the parameter adl_InitType_e from the function adl_main and its value is always 0 (ADL_INIT_POWER_ON from the documentation/header).
I have no exception, no backtraces.
With another fastrack FXT009 (same configuration as above) and the same embedded software, I do not have these reboots.
I would like to know what can cause a reboot of the fastrack with a parameter ADL_INIT_POWER_ON ?
I guess the command “AT+CFUN=1” do it, but this command is not called by my embedded software.
Is that the problem could come from the plugins (WIP or C-OPUS) ?
Any idea ?
