MangOH Yellow OOB can’t connect to octave using GettingStartedGuide

Hi,

I’m evaluating mangOH yellow with which I managed to follow the Getting Started Guide to connect the device and interact directly with it (step 4) without any problem.

When I tried to connect to Octave to obtain sensor data (step 5.2) is when I started having problems as the device were never detected by Octave (device were not in Las Vegas mode).

If I power cycle the device, the Network LED turns green as it starts, then after a moment, the Nwk yellow LED becomes ON (The green one remains on) as it is supposed to happen… right?

After this I start digging on what might cause this for which I:

  • Attached the antenna to the connector labeled as ‘main’, same result.
  • Followed the guides indicating how to update the firmware (yellow_wp77xx_0.5.0-octave.spk) after which I the device did not connect to Octave, even when the procedure indicated success.
  • Investigate on the API to know what happen to the device (where is the list of commands that can be used in a ssh session with the device, so far I only use what I saw people using in the forums?)
  • Using ‘cm radio’ after a reset several times I notice that the radio was not being able to register to the LTE-M network, I notice 3 types of state:

root@swi-mdm9x28-wp:~# cm radio

Power: ON

Current Network Operator:

Current RAT: Module not registered on network, RAT not available

Status: Not registered and not currently searching for new operator (LE_MRC_REG_NONE)

Signal: No signal strength (0)

PS: Packet Switched Not registered (LE_MRC_REG_NONE)

root@swi-mdm9x28-wp:~# cm radio

Power: ON

Current Network Operator: Sierra Wireless

Current RAT: Module not registered on network, RAT not available

Status: Not registered but currently searching for a new operator (LE_MRC_REG_SEARCHING)

PS: Packet Switched Not registered (LE_MRC_REG_NONE)

root@swi-mdm9x28-wp:~# cm radio

Power: ON

Current Network Operator:

Current RAT: Module not registered on network, RAT not available

Status: Registration was denied, usually because of invalid access credentials (LE_MRC_REG_DENIED)

Signal: No signal strength (0)

PS: Packet Switched Not registered (LE_MRC_REG_NONE)

After this, I saw people communicating directly to the modem using AT commands, for which ‘microcom’ is used: ‘microcom -E /dev/ttyAT’

however, if I use this I get the following message:

root@swi-mdm9x28-wp:~# microcom -E /dev/ttyAT

microcom: invalid number ‘/dev/ttyAT’

I have been reading all day about how to know what my problem is to get the out of the box demo to work without success and at this point I think I need a bit of help.

Additional info that might help:

Hi Luis, I am fixing the activation issue on your Yellow currently.

the yellow_1 is activated now.
Can you power it on again and see if it connects?

Hi,

I can connect with mangoh_y_01 now, thanks!

Hi Luis, good to know. I did the same fix on the mangoh_y_02.
