SMS & GNSS With U137 Resource Contention?
-
Does anyone here have any experience with U137 using GNSS and SMS code at same time.?
SMS works as it should if you do not power on GNSS and GNSS works as it should if you do not have any SMS code in your loop. Some sort of resource contention I suppose.
Anyway, has anyone else experienced this or know about it?
Thanks.

Hello @lenswerks
afaik Unit CatM GNSS (U137) uses a SIM7080G which can not use both, a LTE and GNSS, at the same time due to some shared RF circuitry.
See this posting on Stack Overflow.
Thanks

@felmue Thanks for letting me know. Too time consuming using U137 to go any further trying to get Google map with SMS. Maybe another day.
Easier to just use GPS V2 module M003-V2 and hot spot in vehicle with some email or BOT code which works great.
I did use this GPS V2 module to send GPS data to Adafruit IO mapping and included a IFTTT trigger on AIO that would SMS map of current location with Google voice command.
Also, used this module with core2 to email location map every X seconds.
Anyway, I appreciate your posting, letting me know about this limitation.
