eCall sample app runtime problems



I have built the eCall demo sample application (under dev studio 3.6) and run it on the MangOH board using ‘app start eCallDemo’, followed by ‘execInApp eCallDemo trig 2’.

  1. I had to modify eCall.c to remove le_ecall_SetPsapNumber, since it would always fail and terminate the app (I set psap directly in modemServices config instead).

  2. The eCall fails with the attached log output. At timestamp 15:30:12, the trigger can be seen. During the same timestamp period, the log shows:
    Feb 9 15:30:12 swi-mdm9x15 user.emerg Legato: EMR | modemDaemon[20692]/modemDaemon T=main | le_ecall.c le_ecall_Create() 1401 | eCall object was not initialized properly.

In the only source code I can find - legato-af/components/modemServices/modemDaemon/le_ecall.c - ecall_Create() just returns the above error without any other activity. I guess this is not the target code?


cm sim shows ‘inserted and unlocked’.

eCall is not a supported feature on the WP85 module. To use eCall you need an AR module (for automotive applications)
