GPy with Hologram.io SIM
-
As a first step maybe try:
lte.send_at_cmd('AT+CGDCONT=1,"IP","hologram"') lte.attach()to set the APN correctly
-
I've modified the program as recommended; still does not attach to the tower.
Hologram technical support has verified that the SIM should work with the GPy and CAT-M1 connecting to both Verizon and AT&T.
Any ideas of what I can do to troubleshoot further?

@tlanier
I'm really not sure about Hologram with our modules in the US, but lets do the basic checks first:- Have you connected the LTE antenna to the correct port - for the GPy should be next to LED
- Have you waited enough time? - sometimes it can take up to 45 seconds to attach
- Maybe reception isn't very good in your area - Cat M1 coverage is still limited. Try elsewhere or ideally outside.
-
Hologram tech support indicates that their SIM card should work with Verizon and AT&T with your GPy device. They've indicated that they have a GPy and will try the test at their site.
Yes, the LTE antenna is connected to the correct port.
Yes, I've waited many minutes at 3 indoor locations (work and home) and 1 outdoor location with no successful attach to tower.
A cell phone shows the Verizon signal strength to be 3 bars.
Any other ideas of what I can try?
Are there any modem commands that would help understand what is taking place?
-
Hey Jose,
I've been testing it on a GPy, FiPy I have here. Is there an exhaustive list of the AT command set available anywhere? I'm also tracking my progress of troubleshooting on our forum where @tlanier also posted: https://community.hologram.io/t/pycom-gpy/1664
-
Ok thanks @tlanier
Can you try replacing your LTE attach code with:
lte = LTE() send_at_cmd_pretty('AT+CPIN?') send_at_cmd_pretty('AT+CGDCONT=1,"IP","hologram"') send_at_cmd_pretty('AT+CFUN=0') send_at_cmd_pretty('AT+CEREG=2') send_at_cmd_pretty('AT!="clearscanconfig"') send_at_cmd_pretty('AT!="RRC::addscanfreq band=4 dl-earfcn=2175"') send_at_cmd_pretty('AT!="RRC::addscanfreq band=12 dl-earfcn=5095"') send_at_cmd_pretty('AT!="RRC::addscanfreq band=13 dl-earfcn=5230"') send_at_cmd_pretty('AT+CFUN=1') while not lte.isattached(): time.sleep(1) send_at_cmd_pretty('AT!="showphy"') send_at_cmd_pretty('AT!="fsm"') send_at_cmd_pretty('AT+CEREG?')This will produce a lot of debug output
-
Thanks @chrisgammell !
The only AT command guide we can publish is this: https://docs.pycom.io/chapter/datasheets/downloads/Monarch_4G-EZ_LR5110_ATCommands_ReferenceManual_Rev3_NOCONFIDENTIAL.pdf
But really that should be enough, Sequans doesn't share the special AT!= commands even with us other than to solve particular problems.

@tlanier, did you check that command on yours?
-
Yes, I'm also getting +CSQ: 99,99

Thanks @chrisgammell
Can you try this instead please:
send_at_cmd_pretty('AT+CFUN=0') send_at_cmd_pretty('AT+SQNCTM="verizon"') send_at_cmd_pretty('AT+CGDCONT=1,"IP","hologram"') send_at_cmd_pretty('AT+CEREG=2') send_at_cmd_pretty('AT+CFUN=1') send_at_cmd_pretty('AT!="showinit"') while not lte.isattached(): time.sleep(1) send_at_cmd_pretty('AT!="showphy"') send_at_cmd_pretty('AT!="fsm"') send_at_cmd_pretty('AT+CEREG?')The AT+SQNCTM="verizon"' setups up some other parameters for Verizon including scanning the correct bands. These should be reflected in the new debug command AT!="showinit" after CFUN=1

Notice the first command (AT+CPIN?) generates an error.

Can you leave it for a minute or so please. You should see this changing to SCANNING but it's not immediate, it's done in cycles. Thanks.
-
Looks like mine just needed to cycle a few more times as well, just got this:
+CEREG: 2,5,"CC14","031D4803",7
-
That's great! 2,5 is what we want for Hologram (5 means attached as roaming)
So does the
while not lte.isattached():loop finish correctly then and move to the connection step - which means PPP is established?lte.connect() while not lte.isconnected(): time.sleep(1) print("Connected!") -
Mine has been running for about 10 minutes returning:
+CEREG: 2,0
My cell phone uses Verizon and it shows a strong 3 bar signal.
I'm going to try powering down and back up to see if that will help.
-
After power off/on I'm now getting +CEREG: 2,4
It never gets the 2,5 you mentioned after 10 mins.

Maybe Cat M1 coverage in your area just isn’t very good yet, Verizon only uses one band (band 13) for Cat M1 while on mobile phones they support more. -
Do you know if Verizon publishes a coverage map for CAT-M1?
Maybe I should try taking the device to a larger city (Newnan or Atlanta) to see if it works there.
This is what it displays at the start of the test:
