Hi all
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.
RDY
+CPIN: NOT INSERTED
+CFUN: 1
AT
OK
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.....
Thx
MrLudvig

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.

Hey Guys,
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
Hi
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 :
+CPIN: READY
but haven't managed to reproduce this again :(
Keep at it an let me know how you get on....
Best
