HI

SIM7600E module plugged in kc868-A8S v2.0 , running KCS 2.2.2.

cannot send message,
cannot receive message (crash/reboot when message is received)
cannot receive call
can only place test phone call

also :

the SIM7600E module was successfuly tested with an usb-to-Serial converter and putty. --> the SIM7600 module works fine, can send/receive messages
I also tried Tasmota on the kc868, impossible to establish connection to the SIM7600 in serial bridge --> Issue with RX/TX GPIO13/GPIO15 ?

upload your GSM setting screen in KCS.

please find here below the screenshots.

+324xxxxxxxxx is my mobile phone number (I hide the digits for privacy reasons ;-)

so I can do a test call to my mobile, but anything else fails (outgoing test SMS, incoming control SMS, outgoing notification SMS)

***admin*** · 08-30-2024, 01:28 PM

do you have set the SMS service number in your mobile phone. just when the SIM card have normal SMS function when using in your mobile phone?

yes, i tried the exact same hardware combination ( SIM7600E module plugged in kc868-A8S v2.0 ), but with Tasmota32 instead of KCS 2.2.2. , and I can manage to send and receive SMS.

so the problem is with KCS 2.2.2

***admin*** · 08-31-2024, 12:47 AM

ok, next week we will test with KC868-A8S v2 board. if have bug, we will feedback to our software team.

***admin*** · 09-06-2024, 01:27 AM

we have tested with new KCS firmware V2.2.4 here is download link:

important: make sure when you enabled GSM, you MUST need click "SAVE" button for reboot. Then you can use TEST with SMS or CALL.

The problem is most likely related to the power supply of the SIM7600E module.
As it is written in the datasheet for this module, it requires 5-10V DC.
However kc868-A8S v2.0 only supplies 4V DC to pin V.
SIM7600E uses a 1084 (or analog) linear regulator in the power circuit with some voltage dropout. As a result, the SIMCOM chip does not have enough power.
This can lead to cyclic reboots and other bad things.
Colleagues from KinCony, can you explain the situation?

***admin*** · 11-30-2024, 11:34 PM

A8Sv2 resistance R31 now is 2.26K, you can replace with 3K. Then it will output 5v for GSM module.
Yes, use 5V will be better.
