Unable to bring up the network!

Hi,

sometimes the connection is not successfully established, so that the module no longer works.

Unfortunately I don't use the following options: U_CFG_APP_PIN_CELL_ENABLE_POWER U_CFG_APP_PIN_CELL_RESET U_CFG_APP_PIN_CELL_VINT

What other option is there to reset the module via software?

[RobMeades]

Hi Alex: it would depend on the nature of the "no longer works".

If the module is responsive to AT commands then you can call uCellPwrReboot() and ubxlib will tell the module to reboot via the AT interface.

However, if the module is not responding to AT commands, the only way out that I am aware of would be a physical connection to either the PWR_ON or RESET_N pins of the module from one of your MCU pins; this could be done using any GPIO that you control of course. You should check the SARA-R4 System Integration Manual for details of exactly what you need to do with those pins to effect a reset.

ok nice, thanks for the info!

Hi Rob,

to use uCellPwrReboot() do I need u_cell_pwr.h? but then comes the following

[RobMeades]

Hi Alex: yes, you'll need to #include u_cell_net.h just before u_cell_pwr.h. We've removed this problem in the 1.0.0 release that we are about to make by just dumping all required headers into one ubxlib.h that you can include.

Thanks Rob, it works very well!

Hi Rob, I run the uCellPwrReboot(devHandle, NULL); , but the device still does not turn on

Can't remember whether we resolved this one or not now, maybe in direct comms? Gonna close it - please re-open if there is still an issue.
