[Ovmsdev] 3.2.018 release

[Mark Webb-Johnson]

Craig,

From what you sent before, it just seemed that the PPP link could not be established. The CSQ figures you show below indicate the dev board has a better signal (and production is marginal):

Value	RSSI dBm	Condition
2	-109	Marginal
3	-107	Marginal
4	-105	Marginal
5	-103	Marginal
6	-101	Marginal
7	-99	Marginal
8	-97	Marginal
9	-95	Marginal
10	-93	OK
11	-91	OK
12	-89	OK
13	-87	OK
14	-85	OK
15	-83	Good
16	-81	Good
17	-79	Good
18	-77	Good
19	-75	Good
20	-73	Excellent
21	-71	Excellent
22	-69	Excellent
23	-67	Excellent
24	-65	Excellent
25	-63	Excellent
26	-61	Excellent
27	-59	Excellent
28	-57	Excellent
29	-55	Excellent
30	-53	Excellent

I am not aware of any limitation / restriction on inactive PPP cellular data connections - I guess that would depend on the configuration of individual operators. Can you configure the dev board to send some data?

I am not really sure how to help here, seeing the little extracts of logs you send and not knowing your environment. From a troubleshooting point of view, the logs should show the cellular activity and behaviour of the modem.

Regards, Mark.
