Im trying to get my dronecell up and running.
i have connected the cell through TX0/RX0 Ardunio 2560. Serial connections is working.
It respons to my AT command, but during startup it throwing CPIN NOT DETECTED.
I belive it not sensing the sim card.
+CPIN: NOT INSERTED
Tryed to remove the sim pin, and also with diffrent working sim cards.
Also tryed with several diffrent power supply.
I measured the SIM_VDD with my fluke, and during startup i got 1,1v.
However im not sure if my voltmeter is able to sense the peak correctly, due to short periode of time the VDD is powered.
It should be 1,8v / 3,0v / 5..0v depends on wich sim card im using.
Im using the latest Firm..
Any help would be great.
Im running out of options.....
I'm no expert either - but I'm having the same issue. I'm now powering the Dronecell via an ESC. I have a thought it is to do with the gate closing and making a connection when the sim is inserted - in fact during fiddling with this I managed to startup and get :
but haven't managed to reproduce this again :(
Keep at it an let me know how you get on....
i have 2 drone cell boards and have exactly the same problem have tried with 4 different operator sim cards with no luck at all, i have contacted the manufacturer narobo no answer from them either
Good to hear from you Marc
This issue must be either a manufacturing fault or similar.
Have we let the honchos at DIYDrones / the store know?
They've always been super helpful in the past.
i have sent a message to chris to see if he has heard any problems, i will let diydrones know as well its friggin frustrating have spent hours on this :)
could this be a UK thing?
no its not a friend of mine bought this board a month before me and its working fine, looks like it could be a bad batch, did you get yours recently?
Ohh man am I glad I found this thread. I have been trying to figure this out for two months now. I sent my old dronecell back for testing, and after a month and a half, they just sent me a new one. I'm playing with it now. Still no sim card detected. I tried talking to ERIC FORKOSH, don't waste your time. After many emails, just a one liner response saying nothing useful.
had a word with 3drobotics, looks like its a bad batch so looks like they are being sent back lets hope the replacements arent duff as well
Thank you, I don't know about you guys, but I"m done messing with this dronecell. I'm going to go with one of these, they are cheaper.: http://www.elecfreaks.com/store/gprsgsm-moduleefcom-pro-p-450.html

Have u disabled the pin code query with cellphone before inserting the sim to dronecell?
