Sim Cycling

Hi,

I seem to be getting something quite strange happening.

Below I am requesting this information with approximately 6 second intervals.

For some reason, it’s like the module loses communication with the sim card. Although this is the second module that is doing this.

I have also observed a cycling 30mA to 40mA difference which seems to coincide with this loss of communication. 3 seconds, 5 seconds, 3 seconds and so on.

Many thanks

Hi,
which module are you using? also FW version??

-Alex

Here is the string from the module

RHL85xx.5.5.8.0.201411141939.x6250_1
2014/11/14 20:12:05
r2818

Elliot,

5.5.8 firmware is extremely old, you need to be on 5.5.14 as a minimum, this is the current production standard. Geoff is going to send this to you tonight, hopefully this will resolve your issue.

Regards

Matt

Thanks Matt.
