I’m in problematic situation where I can’t understand if my communication errors are due to network provider or due to modem. It would be helpful if others could comment on their success using NB-S1 with their operators. Maybe I can understand better from your examples.
My network operator supports only NB-S1 and only control plane optimization. I’m trying to send UDP packets to my test server. This test was performed with HL7800 using eval board.
I can create UDP socket and send one packet, but then next packets are lost. Then about 10s from first packet, I can send one more. There seems to be 10s ignored interval between packets. What is interesting, that 10s is exactly the period before my operator releases RRC due to inactivity. Looks like it is somehow connected.
Also I have done same tests on other two brands of NB modems and on has the same problem, but other doesn’t loose packets only delays them for up to 10s.
I would like to hear if others can send UDP packets using NB without these kind of problems one by one with small intervals. Especially if using control plane optimization.
