Monarch Go Documentation

TMS_Matt
TMS_Matt over 2 years ago

Where can I find the documentation for the Monarch Go module?

I am looking for details specific to the module itself:

  • AT commands reference. I assume most generic AT commands will work, but is there a list of chip specific ones?
  • Mating connector part number and pinout. Mechanical drawings for the module footprint would be helpful too.
  • Electrical specifications. I recall seeing that the UART interface is 1.8v, can anyone confirm this? Is it 3.3v tolerant or does it need a voltage shifter?
  • Lastly, is there a schematic or pinout available for the arduino shield? I don't plan to use it on the end product but it will help with prototyping.

Thanks for any help! I have looked all over the verizon and avnet websites and found nothing. Even the link of the quick start card in the box (avnet.me/MonarchGo-Shield-GSG) seems to be dead. Very frustrating!

    OK, I finally found some useful documentation here:

    /products/devtools/avnetboardscommunity/monarch-go/m/files

    Which answers most of my questions about, however I am still looking for an AT reference. The uBlox one I have should work for generic commands but is there one for the Go module?

    Thanks, I guess I will have to take up the search with sequans. That was going to be my next step anyway but I figured I would see if I got anything on here... I can probably get the module connected with those examples, but I would really like a complete reference!

    If there are representatives from either company reading this: This is atrocious customer service. You advertise a turn key cellular device and then hide all the useful documentation. Why on earth would I need to sign an NDA for an AT command reference manual??? Most every other company has that linked on the product page of digikey! These aren't trade secrets, half of the AT commands are generic anyway! I shouldn't have to spend hours sleuthing and jumping through hoops just to get some data sheets!

    And then when I email avnet asking for the documents that are not only missing from their proper place: the *product page*, but also the dead link from the quick start card that came with the product. I get a canned email response along the lines of "we don't care enough to provide customer support for out products, we let our other customers take care of that for us, take it up with the forums". I'm not looking for 1 on 1 diagnosis, I just want some TM's and if they bothered to actually READ my email that would be obvious and they could have forwarded the requested documents!

    I am done with this rant, and I apologize for polluting the forum with it, I just hope that it may serve as a warning to anyone else considering integrating this product into one of their own. I can only imagine what kind of terrible support I would get if I had an actual technical issue! the ONLY reason I am stuck with this module is because my client is stuck on verizon and verizon feels it is beneath them to deliver SMS from devices using numbers from services such as Hologram . More scummy business practices from the corporate world... Otherwise I would be using the uBlox module that actually provides easy access to their documentation!

    Once you are over the rant Blush: it's actually a great product. As a modem, but also when you dig deeper and find that it has an embedded MQTT stack <3

    I have experience with this unit with "not verizon" sim cards (2 different providers, in Europe, with every setting different from Verizon). It takes effort and changes in the AT commands - and in my case a firmware upgrade of the Go (and an additional debugger to load that firmware that AVNET kindly shipped to me at no cost).

    If you are able to post your difficulties on the public forum here, I'll try to help.

    I would probably have discovered that if I had access to their sacred datasheetsUpside down

    Conceptually I LOVE the idea and was very excited to try out this module! My use case is extremely simple I just need to fire off a simple SMS when certain conditions are met, and all of that is handled by the host MCU. Under normal circumstance I would already be done with the code but I haven't even gotten started because all of these documentation shenanigans.

    Sequans won't let me register for their site because they don't like my email domain so I guess I will just start blindly throwing code at this thing and hope some of it sticks to the wall!

    (accidently flagged your post as spam instead of replying - hope it survives)

    They rejected my email too, but I contacted them and AVNET, and that sorted it out

    May I ask through which portal you contacted them? I tried avent and they just sent me here with a canned email. I'm not seeing any contact info for sequans, everything just redirects to their cloud support portal.

    summary: your pain now was my pain then. Beyond the heavy curtain of unneeded secrecy,and having no clue of what it is being a customer/user, there is a great product hidden. And many many emails.
    If challenged, I'd be able to calculate how many man months it took me to solve issues that I'd solve in a day if they would care to communicate. Always because there was a reason not to talk. Not because I didn't provide info / details / traces. Corporate.

    I appreciate your input and for taking on the support role that the multi million dollar tech companies couldn't be bothered to provide themselves Pray And perhaps the silver lining of shared suffering being more palatable  Joy

    Hopefully one of these engineers that supposedly frequent this forum will be along some time to provide additional insight
