Hi Shannon and Sara,

Thanks for taking a look at this. I actually JUST fixed it, and I’m not sure what I did correctly?

Nothing I did was able to wake the modem, and like Sara said, it wasn’t receiving power. I was in the midst of taking those photos you request Shannon, and I think just unplugging everything and plugging it back in fixed it……[Read more]

Hi,

Thanks for the quick reply! I am not getting any red lights on the modem at all. I have the Mayfly plugged into my pc right now and the only lights are the orange charge light, the USB/POWER lights, and D8 is lit up as green right now.

Also double checked hologram.io to check to see if the sim is active, it is. I’ve also tried swapping the battery out, taking the sd card in/out, and have messed around with

const int8_t modemVccPin = 18;

and have swapped it from 18 to -1 as per the commented code, but it has not worked.

I’ve generated, formatted, and…[Read more]

Hi,

We’re looking to buy new 3.7 V 4400 mAh batteries for our Mayfly 1.1 and it seems that both the Adafruit and the Digikey vendors on the parts list table are both sold out. Any recommendations on replacement batteries that we could look for or are we okay with buying any general 3.7 V 4400 mAh batteries we can find that have similar…[Read more]

Funnily enough, I’m having the exact same issue! Also using the ClariVUE 10 turbidity sensor. It seems that the logger is writing to the SD card instead of connecting to the SIM. Hologram is basically telling me the SIM is online and ready to be communicated with, it just isn’t receiving anything.
