Thank you!

@neilh20 The most recent one I purchased was: https://www.digikey.com/en/products/detail/revx-systems-corp/251/1998-251-ND/10484959
However, the volunteer determined that AT&T served his site best, so I have not tested nor deployed this SIM.

Best,
Matt

Yes, it’s working again. Thanks.

We purchased NimbeLink’s Verizon SIMs, and we activate them and purchase service directly from NimbeLink, so never had to deal with Verizon itself.

I did contact SIMCom (maker of the modem chip on the LTEBee modems) about Verizon certification, and they said they were still awaiting it. Then they notified me once they received Verizon…[Read more]

Ah! Thank you @heather! I had already forgotten that notification after a week – yikes!

OK, I received the password reset email; it just took a bit longer than expected.

However, after using the reset code and entering a new password, I got the error attached below. (Page URL is: https://monitor-my-watershed.auth.us-east-2.amazoncognito.com/error)

We’ve had success using the EnviroDIY modem on Verizon (though I recognize that the modems are currently out of stock). See this thread for details on the SIM and APN.

Any estimate on when the LTE Bee modems will be back in stock, either here on EnviroDIY or on Amazon? -Thanks.

I don’t have a ton of experience reading schematics, so I could be in error here. But FYI, it appears there may be an inconsistency in the v1.1 rev A schematic regarding the part number of the LiIon Charger chip. Please see attached screenshot. (Also understanding that these things are a moving target as chip availability changes.)

FYI, just noting here that the  Hardware Status and Availability page is not up to date, at least with respect to Mayfly board availability on Amazon, as they are out of stock.

I’ve confirmed that the Verizon SIM we used was this one, from NimbeLink:

@jamesbailey I’ll check with my colleague to find out exactly which SIM he used for the test; he’s in the field for a few days. My test code is based on https://github.com/EnviroDIY/ModularSensors/blob/master/examples/DRWI_SIM7080LTE/DRWI_SIM7080LTE.ino, and the only modem-related code change I made was to the APN.

-Matt

Hi @neilh20, I believe the SIM we used was a RevX.

The SIMCom 7080G modem chip upon which the EnviroDIY LTE Bee is built did not have Verizon certification until early August. Once they notified me, I asked SIMCom support what APN setting to use for Verizon, and this was their response:

Set you APN as…

OK, got it, thanks.

I’ve made the hardware and software modifications you recommended and all seems to work perfectly.

Thanks again.

Thanks for this excellent detail.

So we could continue to use the LTEBee adapter with the Digi modem on a v1.1 Mayfly, which would retain the functionality of the white and blue modem status LEDs, and would connect the Bee socket’s pin to the proper status pin on the Digi (without need to modify SJ19), and we would not need the power jumper to…[Read more]
