About the Document
Revision History
| Version | Date | Author | Description |
|---|---|---|---|
| – | 12/1/2022 | Herbert Pan | Creation of the document |
Foreword
In this document, it illustrates how to capture DEBUG log on BC20/BC26/BC66 Series under LPWA modules. In addition, it can be available to capture DEBUG log of such above modules in a fast and effective way via this document. Finally, it can be implemented on relevant applicable analysis based on certain contents.
1.1. Scope
| Tools | Manufacturer Revision | Applicable Module Type |
|---|---|---|
| Genie | AT+CGMI/MTK_2625 | BC20/BC26/BC66 |
1.2. Download
GENIE
MT2625_nbiot_tools_20220930_exe_V1.2240.5.zip
Note: The tool has a validity period. If it has been expired when
deploying, please feel no hesitation to contact with Quectel.
1.3. Device Connection
If the module has been welded or debugged separately, it is recommended to
connect to the Genie and capture log as shown below.
Under the circumstance that the TE-B corresponding to MTK module is deployed, please select the second COM port in the “Port” under the drop-list of “Device Manager” , which means the “Silicon Labs Quad CP2108 USB to UART Bridge: Interface 1” will be used to serve as GKI port. While the third COM port, Silicon Labs Quad CP2108 USB to UART Bridge: Interface 2, will serve as HSL port.
Installation
Being installation-free, the Genie can be used after being unzipped. Run Genie.exe in the directory of MT2625_nbiot_tools_20220211_exe_V1.2207.5\nbiot\tools\core\genie.
Connection
Click the genie icon above to start, the initial display is as shown below; Select “New Config” for related settings.
3.1. UART Connection
The GKI (mandatory one) corresponds to Debug port. While the HSL (optional,
untick it if the AUX port is not induced) corresponds to AUX port. In
addition, the .defile in the corresponding firmware file is imported into the
Database.
As for configuring baud-rate, run the AT command “AT+EPORT=4” to query the
supported UART port in current module and configure according to the returned
value and corresponding table
If it is needed to modify the baud-rate of DEBUG port, please refer to
following AT command and corresponding configuration list.
AT+EPORT=3,2,
| +EPORT: | 0 | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|---|
| UART | UART | UART | UART | USB | USB | |
| variable | 921600 (fixed) |
Genie Baud-rate Configuration（AT+EPORT=4）
Baudrate_index| Baud-rate=| 0| 1| 2| 3| 4| 5|
| Baud-rate| 110| 300| 1200| 2400| 4800| 9600|
Baudrate_index| Baud-rate=| 6| 7| 8| 9| 10| 11| 12
| Baud-rate| 19200| 38400| 57600| 115200| 230400| 460800| 921600
3.2. USB Connection
If the USB is used to output Log, please execute AT commands and set as shown
below; It is recommended to disable USB output via relevant commands after the
log is outputted.
Open USB output
AT+EPORT=1,uls,5
AT+EPORT=1,emmi,4
Close USB output
AT+EPORT=1,uls,2
AT+EPORT=1,emmi,1
After above steps, power on or restart the device to take effect. The ports
displayed in device Manager are as follows:
It is available to modify and save configuration parameters via corresponding icon in the toolbar as shown below, or by “New Config” / “Save Config” in the drop-list of “Config”.
Then, click the icon in the toolbar as shown below to start recording log;
Note: After the device is powered on, it is necessary to call POWERKEY to
power on the module.
Subsequently, the window will display as follows.
As shown below, the engineering mode in Genie is enabled to facilitate the observation of the signal reference received by the terminal.
As shown below, open genie signaling window via the “RRC Decoder” in the drop- list of “Special”, it is convenient to observe the terminal signaling interaction;
Save Log
4.1. Manual Save
After the log is captured, save the log by “Save As” under the menu of “Log”.
Common Analytical Application
5.1. Import Log
It is available to open log via clicking the saved xxx.glp file or initiating
Genie. See next figure for details.
5.2. Hue the Message
By using icons in the toolbar as shown below, different types of Log messages
can be hued with various colours, which makes it easier to identify and query.
5.3. Filter Log
Open the Find/Search window shown via icons in the toolbar below, or the
“Find” hidden in “Edit”. Please note the case options and search direction;
5.4. Data Analysis
Open following window via “RRC Decoder” in menu of “Special”, the message in
NAS/AS layer can be decrypted.
5.5. Export Pcap
Open following window via “RRC Decoder” in menu of “Special”, select “Export”
and refer to corresponding option to export Pcap file
Notes
- If the issue that debugging or analyzing can be attributed to the event of registration, please run AT command AT+CFUN=0/AT+CFUN=1or reboot module/terminal after connecting to Genie to capture the complete registration network process, which can be applied for the possible cause of the failure to current registration network.
