SIM7000E support

I’ve got a EVB with a SIMCOM 7000E, any already figured out if this would work, and what AT commands to use?

SIMCOM 7000E
Hi Mark,
Just looking at the specifications from the SIMCom website:
Specifications for Data transfer
• LTE CAT1- Uplink up to 5Mbps,
- Downlink up to 10Mbps
• EDGE Class - Uplink up to 236.8Kbps,
- Downlink up to 236.8Kbps
• GPRS - Uplink/Downlink up to 85.6Kbps
• CSD - GSM data rate 14.4Kbps
I don’t see any of the NB-Iot standards specifically mentioned, so I would be cautious…
Regards,

@techniek Have a look at: http://simcomm2m.com/En/module/detail.aspx?id=168 It says (4G) Cat-M1, (4G) NB-IoT, (2.5G) Edge and (2G) GSM/GPRS.

Aha, based on the HL specs looks promising.
We have not tested this module ourselves so I cant give you a definitive recommendation.
Reminds me to see if we can get an update on the compatible modules list.

@techniek I am trying to use this board. I can get connected to the network but can not send a message. Commands like AT+NUESTATS, AT+NCDP=172.16.14.22, AT+NCONFIG=CR_0354_0338_SCRAMBLING,TRUE, or AT+NSMI=1 and AT+NMGS=11,48656c6c6f20576f726c64 do not work (ERROR). Is it still possible to use such a module to send messages to the CDP? Could you give an example?
-
Regarding the AT commands, things to check.
-
Check if you have set the ocieanconnect APN. (In the manual parts 0 and 1 below you will see a few examples)
Some devices need a reboot in order to make the APN persistent…

Scrambling, try to see if you can set it to FALSE…
-
Device registration, is the device visible in the devreg tool, maybe delete and reregister with the IMEI of the device?

Hope this helps…
