1. F.A.Q.
| Questions | Applicability | Answers |
|---|---|---|
| How do I start? | All configurations | Read this wiki article and the user manuals (UM2567 to get started, and UM2426 for detailed explanations). |
| How do I connect the board? | All configurations | See the Hardware setup article on this wiki. |
| How do I know if the cellular application is up and running? | FreeRTOS | Use the trace on Tera Term see the Echo exchanges. |
| How do I know if the Echo TCP application is up and running? | Azure RTOS | Use the trace on Tera Term. |
| Nothing is displayed in Tera Term. | FreeRTOS and Azure RTOS | Ensure that Tera Term options (such as Baud rate) are correctly set. |
| Wrong Echo in Tera Term during setup. | FreeRTOS and Azure RTOS | Ensure that Tera Term options (such as New-line and Transmit delay) are correctly set. |
| X-CUBE-CELLULAR boots but there is an issue with the network. | FreeRTOS and Azure RTOS | Check that the correct SIM is selected (plastic SIM or soldered UICC). |
| EMnify activation for P-L496E-CELL02 | All configurations | This feature has expired, it is no more possible to activate the eSIM therefore use plastic SIM instead. |
| Why is X-CUBE-CELLULAR not operational after boot? | FreeRTOS and Azure RTOS | There are multiple possibilities: the selected firmware does not correspond to the modem used, the SIM card used is not valid on the available network, the modem firmware version release note, too many bands selected and parsed by the modem (see UM2567). |
| How do I know if the cellular data service is operational? | FreeRTOS and Azure RTOS | Cellular operational after trace displays -----> State : CST_MODEM_DATA_READY_STATE <----- and/or Network is up is displayed. The "cst info" command can be used to know the modem state when trace is deactivated. |
| What is the modem FW version? | All configurations | If you use a modem firmware different from those used in tests, you might have discrepancies. Read carefully the modems release note for detailed information. The modem FW version is displayed at boot. The "cst info" command can be used to know the modem FW version. |
| GM01Q or GMS01Q? | All configurations | Both are Monarch modem from Sequans. GMS01Q is the same as GM01Q, but also includes a soldered SIM from Orange inside the module to allow connectivity without using an external plastic SIM. |
| Is the boot process correctly applied? | FreeRTOS and Azure RTOS | Check appropriate (concerning used hardware setup) chapter on Hardware setup article on this wiki. |
| Why entering commands in cmd line through the terminal can generate issues? | FreeRTOS and Azure RTOS | Commands can be entered manually or using a copy/paste. In copy/paste case, commands must be pasted one after the other. By copying/pasting multiple commands without waiting that the FW is ready to receive, this might lead to errors. For example after “cst targetstate off” command, wait for MODEM_INIT_EVENT event (can last few seconds), then paste the next commands one after the other “cst apnuser on” and then “cst apnconf [<apn> [<cid> [<username> <password>]]]” |

| How to use STM32_Cellular with FreeRTOS | FreeRTOS and Azure RTOS | See How To add FreeRTOS support to Azure RTOS package in How To Wiki article |
