Thanks very much Reuben. I have downloaded and installed the passthrough firmware.
I was able to see some feedback from the modem: “+CGREG: 5 …”
I have couple questions to basically understand how this passthrough mode woks:
1- The system microcontroller talks to the Ublox via UART interface. I believe this is how it sends the AT commands to the modem. These command are received from the User Microcontroller through the UART interface (the one that Dash call as SerialCloud). Please correct me if I am wrong?
2- What Baud rate should I configure my SerialUSB interface in order to properly write on the Serial Cloud? Is it 115200?
3- Is there a special consideration in order to configure and establish the data link with the Hologram cloud? Like a PIN for the SIM or the carrier that I have to choose in order to use my data plan with Hologram Cloud.
4- Why the dash official firmware source code is no longer open? Can we have a copy of an older version? Can we have example on how you interface with the Ublox?
It is a lot of questions, but I think you see now where I am going. I will be very grateful if you can help me with this.
Cheers.
