Hello

After coming back from Paris I have tried to connect with MangOH and I don´t get it.

I don´t have signal level. In Paris I connected OK to Octave. In Madrid with MangOH Red using SierraWireless external SIM I connect without issue.

Mango Yellow is activate in Octave. Do I need to do something in Octave to activate again my board?

Are you using Sierra SIM and is the antenna connected?

Hello Asyal

Problem was that I updated the firmware of MangO Yellow so I lost Octave application. David Clemente of Renfell got Octave firmwware for my MangOH yellow and solved the issue.

Thanks
