My new itracker 8212m is not working correctly

Cellular Boards RAK8212
1

I used a hologram SIM and programmed the downloaded hex for the RUI firmware through nRF Studio. The SIM is shown as live on the hologram site but the modem does not respond to AT commands. You just see the RDY response again and again in J-Link RTT viewer.
Obviously I can’t upgrade the BG96 firmware with the DFOTA.
I get the same behavior with mBed programming. So the BG96 must be defective. Not sure what the return policies are. I am very frustrated.

Hi,
We have provided a test demo for hologram. Before compiling, you should change options in Makefile_Custome like below:

Enable hologram
#part 3 nb-iot test, test hologram sim card
#0------off 1------on
ACCESS_NET_TEST = 1

Disable bsp test
#part 6 bsp test, test sesnors on board
#0------off 1------on
BSP_MODE = 0

After compile and download to your device, you can send at command via BLE. Then all messages are shown in RTT.

More details are in RUI_Platform_Firmware_GCC\RUI\doc\ about hologram.

BR,

Nero

I don’t really want to compile anything. I am using the HEX from your website. That should work, right?

4

We have update the hex and you can have a try. All AT cmd is via ble from phone.

5

What is the link for the new HEX? I checked the rakwireless.com/en documentation portion yesterday and it still has the same rar file.

Hi, @sudhir

I’m sorry for that my colleague hasn’t updated the latest firmware on our website today.
I just created a temporary repository on Github, and you can download the latest firmware from there provisionally:
https://github.com/RAKWireless/itracker_firmware/tree/master/itracker/RAK8212

That helped but not completely. The AT commands are received but no output.
Here is the output from the JLink

So if this is a busted unit, how do I get a replacement or my money back?

Hi, I’m sorry the hex on github is not for hologram and I have updated it. You can get from previous github (https://github.com/RAKWireless/itracker_firmware/tree/master/itracker/RAK8212_M/RAK8212_M_v2.0_Hologram.hex). Our test log is below (join in net according to your net operator):
