Where did you get your sim300_dev board from? URL..?

cms error 517

ds18s20, i was looking for an answer, not a for a question The board is not mine, and i will never buy a dev board couse i can do it starting from the module.

Anyway, since i have seen in the forum this and other unanswered questions, i want leave some answers, hope they would be visible on a search.

SIM300 general help

+CPIN: NOT INSERTED
mean that the sim card is not, or probably "not well" inserted. Try to clean the contacts, and keep the card pushed by hand, just for test.

+CPIN: SIM PIN
pin code must be entered, try AT+CPIN=1234

+CMS ERROR: 517 : SM BL NOT READY
sm stay for Sim Phonebook. Anyway this message probably mean that the sim is not well inserted, or that the PIN code in not inserted (try AT+CPIN=1234 )

Receiving bad charachters on the terminal:
This is due to the fact that Sim300 start up as factory default in "autobaud rate". Set it to a fixed speed, for example AT+IPR=115200
The speed will change after the "OK".

sim300 sm bl not ready

I ´m using a EVB but for sim508 and i was the same problem. In my case there was a hardware problem, the Evaluation Board come with a short circuit between sim card voltage and ground.

hi spectrum70
for your problem U must to check first voltage of sim power pin
second be sure sim present pin is grounded
& check the other pin is connected correctly to sim card if u design a board for sim300 show that it may I can help U

hi jul1984 show a picture of your evb board
it may be have mistake on soldering
or design if U make it by your self

best regard

why cfun=1 in sim508

Sabeti_1990 Actually i found the problem, it was a shortcircuit in a capacitor, contecting from Vsim to groung, and for reasons of warranty i could´t try to repair it. I bought the EVB from Simcom.

Greetings.
