Hi team,
We are using EC200UCNAA device and SDK version LTE01R03A04_C_SDK_U
Suddenly during development after enabling DSSS - facing restart issue with following Description on Debug.
pmu: boot mode magic 0x0, por_src_flag 0x13, wdg_int_raw 0x0 reset_cause 0x240000, boot_cause 0x9
We have even tried disabling DSSS and recompile new - still problem not solved
Hi @Inventor_TM,
Can you share the full trace log?
It’s likely that the module restarted due to a panic.
Victor - thank you for quick response - but after new build, problem seems to be solved - i don’t know what was wrong - do you have any document to understand the por_src_flag, reset cause data.
Using DSSS - when i am checking the CSQ of sim0 & sim1 – I am only getting the data from Sim0
please guide to resolve the Error.
Hi @Inventor_TM,
Sorry but I don’t have those documents, they’re usually for internal debug use.
If you wish to test out the DSSS feature, check out ql_sim_dsss_demo() in components\ql-application\sim\ql_sim_demo.c.
Victor.W, I have used the Demo and had received the error - but now solved.
for further testing of the 2 SIM environment - unable to get the CSQ values for Sim1 using API → ql_nw_get_signal_strength (Note: Sim0 we are able to get the CSQ)
My concern is because this is DSSS - only set Sim will provide the results (incase answer is yes) → is it possible to get DSDS firmware / setup to initialize the feature?
Hi @Inventor_TM,
Are you able to get the IMSI of both of your cards using AT commands?
Use AT+QDSIM to select SIM and AT+CIMI to query the IMSI.
This is to make sure that the hardware is good.
My hardware seems to be good as i am getting different IMEI, IMSI and ICCID.
for my application i wish to know signal strength of both the Network providers in realtime and select the Operate ID - (Sim1 / SIm2) in runtime.
is the above requirement is possible to achieve with EC200U - CNAA in DSSS mode?
