Hello. Recently I've been reading blog - pro4people.com and I have to admin that AWS cloud services got my attention. What ERP system would you recommend if we want to use amazon website services? Is it possible to use SAP on this network? Let me know please, since we are completely new to this subject.
@crumble Okay, I'll give that a try. I saw it in an example of exception trapping, and took it to be what would get me out of the try statement, like a C case statement. Apparently I misinterpreted the example code.
Not noticed the lTE issues as this does not work in the uk.
It should keep the almanac and other data when in sleep mode, however the sleep architecture is one where essentially recovering from sleep is a (re)boot, so you need to design accordingly. Also, do not use an SDCard as this will stop the sleep current from going below 5mA.
I have not progressed this for over a year. Sorry.
@misterlisty I don't quite see how 35 KB is a "large file"... There must be something wrong in your setup, it is common to upload much larger files than that to perform OTA firmware upgrades for instance.
Can you give more details about the setup, including whether the module is acting as a station or AP, what you have between the client and the device, any logs shown on either side, what type of file you are uploading...
Tcpdump or wireshark captures could potentially be interesting as well.
I've added the timeout to make the recvfrom non-blocking.Moreover, all the operation does not depend by the s.bind() (for safety I tried to remove it anyway, and in fact it still doesn't work)
