BG95 unable to send data via 2 different APNs at same time

Technical Subjects Software General Function

While using BG95 device, I establish several PDP sessions with different APNs. But at the moment of testing data via a simple AT+QPING, it looks to succeed only via the first of those.

Why device isn’t able to send data via the second,third session?

Hello Alfredo,

Have you actived 2th PDP with AT+QIACT=2 ?

Hi Linkin,

Yes, sure, both PDP contexts are activated with AT+QIACT=2. Actually I see the 2 different IPs assigned properly. This is neither an issue with the specific APN, if I switch my config and I use APN1 as APN2 and the other way around, the one set with the id=1 is working, and id=2 is not.

Kr,
Alfredo

Hi Linkin,

I upgraded FW in my device, and issue was solved immediately.

For your reference I was in R02A02_01.003 and I moved to R02A03_01.017
