Ok here is a different crash..

Hmmmmn, I am actually able to recreate this problem with or without external power. It's some sort of failure with the tx_rx communication between the module and Tessel. I'll dig around in the code for you tonight and hopefully have an answer for you by tomorrow at the latest.

Hi, I got the same issue while trying to send a sms.
Did you find some fix ?
Thanks a lot for the work !
