Support for the Huawei E3276 modem is available on the following products:
- Bond II
- Bond Pro
- Cube Pro
Support for this modem requires:
- current Teradek firmware (minimum of version 7.1.14) from the Teradek download site
- configuration of the Teradek product based on the Huawei modem's mode (Hi-Link / Ethernet, versus non-Hi-Link as a serial or composite device)
We have confirmed support for the E3276-s150 and the E3276-s500. Note that there are several variants of the E3276 (see here for a partial listing of models).
These different models may identify themselves differently in software, which would mean that if they didn't work in the current firmware they could need support added in a future firmware update.
In addition to the model variations at a hardware level, there are at least two software differences in how the modems identify themselves to computers:
* as a Serial device, corresponding to the Custom -> GSM setting
* as a Composite or Ethernet device, corresponding to the Custom -> Composite or Custom -> Ethernet setting; this variation is sometimes branded as a "HiLink" device by Huawei
they may also work in Auto mode
If the E3276 firmware version starts with a "21" then it should act as a serial device; if it starts with a "22" then it should use the Composite or Ethernet settings.
If the firmware on the modem starts with "21", then you would need to use the Custom -> GSM setting with the APN assigned to the mobile carrier's account. The "CID" value should not need to be changed and would be left at 1.
Composite / Ethernet configuration
If the firmware on the modem starts with "22" then you can try either the Custom -> Composite or the Custom -> Ethernet setting.
The Ethernet will be the easier option to try first.
For the Custom -> Composite option you can try the following:
Configuration Mode -> Custom
Initialization 1: ATZ
Initialization 2: AT^NDISDUP=1,1,\"my.apn\"
leave other options blank
Replace my.apn with the APN on the mobile provider account.
If the modem is branded as a "HiLink" modem by Huawei you should try the Custom -> Ethernet option.
