I bought Q2686H
UMT Rev C
FCC ID: O9EQ2686
70546005008530000 008 08 ES
Our distributor send me beta TCP/IP stack B61h09gg.swift files.
I tried to upgrade module (with at+wdwl I loaded dwl.dwl and than b61h_q2686h.dwl), and after this module write BAD SOFTWARE and doesn’t work.
I asked distributor files to reflash module, they sent me pro-dwl.wpb, w.e2p, q2686h.e2p from this version (B61h09gg.swift), and DWLwin 18.104.22.168, but after reflashing I see BAD SOFTWARE again.
I asked them previous version of firmware (b60h), tried to reflash module, but after reflashing I see again BAD SOFTWARE.
What I do wrong?
How to repair my modules?
Whan the final version of TCP/IP stack would be ready for customers?
Another questions: Why Q2686H works correctrly only if power supply is >= 3.75v ? Q2406 works from 3.60v in the same schematic.
