I am testing 3 identical boards equipped with GE863-PRO3 modules. On 2 boards, GSM and GPRS attachment work fine. On the third one, GSM attachement is ok but GPRS attachment is always denied.
Im am using the same SIM card on all boards. The provider told me that the IMEI is not blocked. I have tested with another provider : same problem.
What can I do to find out the problem ?

With #AUTOATT=0, AT+CGATT=1 gives ERROR too and sometimes no response (I used a 2 minutes timeout).
The SIM should be OK because it works on the two other modules.
It seems that the modem is bad, no ? But two weeks ago it was working fine !
You can see on the trace that sometimes, the GSM attachment is very difficult too.
Thank you
Please do AT+CMEE=2 then AT+CGATT=1 again.
Try to swap power supplies and antennas as well.
You’r write, the first CMEE=2 was not on the same cmux instance.
Now we get, with AUTOATT=1 :
00:00:47, AT+CMEE=2 00:00:47, AT+CMEE=2 00:00:47, OK
00:00:47, AT#AUTOATT=1 00:00:47, AT#AUTOATT=1 00:00:48, OK
00:00:48, AT+CGATT=1 00:00:48, AT+CGATT=1 00:00:48, +CME ERROR: operation not allowed
and with AUTOATT=0 :
00:01:27, AT+CMEE=2 00:01:27, AT+CMEE=2 00:01:27, OK
00:01:27, AT#AUTOATT=0 00:01:27, AT#AUTOATT=0 00:01:27, OK
00:01:27, AT+CGATT=1 00:01:27, AT+CGATT=1 00:01:27, +CME ERROR: operation not allowed
We are using the integrated battery charger to charge a 1000mAh battery. Vbat = 3.8V as you can see on my previous post (AT#CBC command).
I will try to change it with a known good 1300mAh battery.
The antenna cannot be swapped because it’s printed on the circuit board (designed by Telit).
Normally we have to mount 3 resistors in PI to adapt the antenna impedance. These resistors are not mounted, there is only a solder jumper, because we don’t know their values yet. It’s working this way on the 2 other prototypes and the CSQ is not too bad (17).
I would try to re-upload the latest firmware in the module, this will reset all settings to default.
Yes but I don’t know how to upload the firmware through the console port. The modem port is only accessible from the ARM processor.
We need a kind of Xfp running on the embedded Linux. Is it available ? I’m afraid it’s not.
What boards have you? You don’t have access to the modem serial port of the GSM engine?
… and please check with AT#REGMODE=1 results of +CREG and +CGRE.
With AT#REGMODE=1 :
00:00:16, AT+CREG? 00:00:16, +CREG: 0,2 00:00:16, OK
00:00:26, AT+CREG? 00:00:26, +CREG: 0,2 00:00:26, OK
00:00:36, AT+CREG? 00:00:36, +CREG: 0,3 00:00:36, OK
00:00:46, AT+CREG? 00:00:46, +CREG: 0,3 00:00:46, OK etc. …
Looks like registration is denied completely.
One more test:
AT+CPIN? and AT#SERVINFO after +CREG: 0,3
and
AT#CSURV
And please investigate the direct access to modem serial port for firmware upgrade.
The trace with AT#CSURV :

Christian, please try and check:
– set verbose error reporting mode: AT+CMEE=2
– change the SIMs between modules and see if SIM or module related
– check GPRS class: AT+CGCLASS?
– check GPRS attach mode: AT#AUTOATT
– check GPRS attach status: AT+CGATT?
– try manual attach: AT+CGATT=1
Thank you for your fast reply.

You can see on the trace that sometimes, the GSM attachment is very difficult too.
Thank you
Thank you for your fast reply.

Thank you
Please do AT+CMEE=2 then AT+CGATT=1 again.
Try to swap power supplies and antennas as well.
You’r write, the first CMEE=2 was not on the same cmux instance.
Now we get, with AUTOATT=1 :

We are using the integrated battery charger to charge a 1000mAh battery. Vbat = 3.8V as you can see on my previous post (AT#CBC command).
I will try to change it with a known good 1300mAh battery.
The antenna cannot be swapped because it’s printed on the circuit board (designed by Telit).
Normally we have to mount 3 resistors in PI to adapt the antenna impedance. These resistors are not mounted, there is only a solder jumper, because we don’t know their values yet. It’s working this way on the 2 other prototypes and the CSQ is not too bad (17).
I would try to re-upload the latest firmware in the module, this will reset all settings to default.
Yes but I don’t know how to upload the firmware through the console port. The modem port is only accessible from the ARM processor.
We need a kind of Xfp running on the embedded Linux. Is it available ? I’m afraid it’s not.
What boards have you? You don’t have access to the modem serial port of the GSM engine?
… and please check with AT#REGMODE=1 results of +CREG and +CGRE.
With AT#REGMODE=1 :
00:00:16, AT+CREG?
00:00:16, +CREG: 0,2
00:00:16, OK
00:00:26, AT+CREG?

00:00:46, AT+CREG?
00:00:46, +CREG: 0,3
00:00:46, OK
etc. …
Looks like registration is denied completely.

We think it’s an HW failure, the
module was probably damaged during the tests. We suggest to contact the
distributor to swap the faulty module.
Ok, thanks for all.
The module is a BGA so we can’t change it easily.
Anyway, it was only a prototype board.
Christian,
