XBee3 LTE-M does not always transfer all data.

0 votes
I have a XBee3 LTE-M module, mounted on a custom board that is communicating with a Cypress PSoC 5, running FreeRTOS 10.1

I'm trying to download a ~150 KB file (a firmware for OTA updates) using HTTP GET, and sometimes it works, but a lot of times the transfer just stops mid way through. I've been running the module at 9600 baud, but I tested at 115200 baud and had similar difficulty. I'm working the module in transparent mode.

Surprisingly, I also have the same difficulty using an XBee Wifi module communicating with a local server.

Are there any procedures or settings I'm missing that can help make the connections more reliable?

Can you wireshark the server side? It isn't unheard of for internet providers (especially cell carriers) to fiddle with tcp or http to 'optimize' it and break things.
