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?
- Yes, you are correct.
2- What Baud rate should I configure my SerialUSB interface in order to properly write on the Serial Cloud? Is it 115200?
- Yes, it should be 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.
- No special consideration, aside from setting the APN to hologram
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?
- I don’t believe we have ever released our firmware yet. It’s always been a goal of ours, but we’ve run into a few setbacks. Rest assured, we are working on it, and expect to have it released in the next month or so. Until then, we likely won’t have any examples available.
