WP7702 will not do cfun=1

after AT!RMARESET=1
the at+cfun=1 command returns
+CME ERROR: operation not supported

what can i do ?

Hi @frini, some factor is preventing the module from going online. Could you check AT!PCINFO? response, to determine what vote is holding the device in LPM? Potential reasons include voltage or temperature out of range, modem software mismatched with configuration, and hardware switch (W_DISABLE).

Thanks,
Ryan

Hi Ryan,
Thanks for your help.
the AT!PCIFNO returns the following:
State: Low Power Mode
LPM voters - Temp:0, Volt:0, User:0, W_DISABLE:0, IMSWITCH:1, BIOS:0, LWM2M:0, OMADM:0, FOTA:0
LPM persistence - None

OK

what does it mean ?

I checked in the forum for similar answers and i also checked AT!IMPREF?
!IMPREF:
preferred fw version: 00.00.00.00
preferred carrier name: NONE
preferred config name: NONE_000.000_000
current fw version: 02.16.06.00
current carrier name: GENERIC
current config name: GENERIC_001.013_000

fw version mismatch
carrier name mismatch
config name mismatch

OK

and also at!image?1
TYPE SLOT STATUS LRU FAILURES UNIQUE_ID BUILD_ID
FW 1 GOOD 127 0 0 001.028_001 02.16.06.00_GENERIC
FW 2 EMPTY 0 0 0
FW 3 GOOD 127 0 0 001.026_000 02.16.06.00_ATT
Max FW images: 3
Active FW image is at slot 255

TYPE SLOT STATUS LRU FAILURES UNIQUE_ID BUILD_ID

OK

It seem to have a missmatch. but AT!IMPREF=“GENERIC” results in error (after typing the password)
can the parameter be updated from the linux shell (ssh)?

Thanks @frini. For image preference, could you take a look at this thread?:

The one-click tools for Windows, distributed by Sierra, should set the preference. If re-applying the modem firmware image doesn’t help, could you provide a few more details?
ATI ->I’m just interested in the FW version, from this response
AT!PRIID?
AT!CUSTOM?

Thanks,
Ryan

The windows tool doesn’t work (it did before the problem occurred) . it writes:
Primary error code: 51 - Failed to switch device to BOOT&HOLD mode.
Secondary error code: 201 - Failed to switch device to QDL mode.
Device error code: 0x0 - Unknown device error code.

I was on the way to install the SDK and try swiflash but i have restart the PC and change something in the boot of the PC and unforchantly it is a remote PC and i will have access to it only next week.
So, until than only at commands can be used…

Success!!

C:\Users\xxx\AppData\Local\Temp\RarSFX0>fdt2 -f WP77xx_Release9.1_RC5_GENERIC.spk
