Friends,
I am using MCU with Siemens C35 for data transmission/reception.
If cellphone uneventually switches off, MCU hangs & stops executing its instructions.
Can anyone helps me to resolve the issue.
Regards,
How do you know that the processor hangs when the phone is turned off? Isn't it more likely that the processor is turned off too? Isn't the processor _expected_ to stop running your application in case the phone is turned off?
So, ask Siemens why the phone turns off, or try upgrading the software, or send it to a repair center, or stop sending shutdown commands to the OS.
Are you saying that you are using Keil development tools to develop software for the Siemens phone? If not, it would be many times better to ask for help in a forum dedicated to development of software for Siemens phones...
