Hi all, I’m attempting to use the boron LTE in a low power sensor logging application. We record 16 bit int’s at 100 hz then send that data on the hour. it comes out to about 720 kByte. I’m trying to reduce as much power as possible obviously, I use an external mcu to do the sampling and timing, then I boot the boron to sendoff the data. Problem is that theres a data rate limit of the publish fxn. 620 bytes per second turns into about 20 minutes of on time to send off this data this is a lot of on time for the boron, I was hopping to get that into the range of a couple minutes, just aquire and send as one big packet. I understand that this is not the fastest chipset on the market but the datasheet for the modem advertises 60kbit > 7kByte speeds for the narrow band edition, are these attainable in this implementation?
one option would be to publish to the modem then sleep the mcu while the data is sending, this is good but not great as the sleep current is still pretty high… I’m pretty sure a larger bw modem would be more efficient in terms of joules/byte in this application. Is there another version with a different modem?
Even so, I’m not seeing the data rate advertised in the ublox datasheet, does anyone have any ideas on how to attain that?
