 h2. Participants 

 Just one: <>. 

 I camp on freenode IRC #osmocom so feel free to get on there and ask a question. Might take a day or two for someone to reply but if you stay on they usually will answer. 

 h2. Goals 

 * Help with documentation, testing, troubleshooting via email/irc. 
 * Research and develop 3G baseband on mediatek chips 
 * Test postmarketos/ofono on Moto E (surnia) and LG Nexus 5 (hammerhead) 
 * Play around with qualcomm quectel modules 

 h2. Details 

 * debian linux 
 * EC20 module 
 * iPhone 4 
 * various other 3G+ phones to test with 
 * ZTE Obsidian phone - MT6735 - GSM, UMTS, GPRS, HSPA+, HSUPA, TD-SCDMA, EVDO, LTE Cat 4 (based on 

 h2. Journal 

 * 04/10/2020 
 ** wrote some CFEngine policy to setup raspberry pi as nitb 
 ** struggled with NTP issues for a while but finally after some good config and a nano3g reboot things are connected! 
 ** trying to make calls/send SMS fails right now. Will email mailing list with logs and config to get some clues 
 ** really need this network to support my testing of ofono on postmarketos on hammerhead (LG Nexus 5) and my fork of termux-api which supports sms/mms 
 ** plan on trying to find some open source MMS gateway to integrate with osmocom nitb (as mentioned previous update) 
 ** will try and publish the CFEngine policy and write a blog post about the experience 

 * 03/04/2020  
 ** restarting my efforts to use this setup. Working on a raspberry pi with packages to setup 3g network for 
 ** wireless connectivity between a kindle DX and other devices in the home 
 ** testing sms/mms/group/image/attachements with my hack for command line support in termux android app: 
 *** will need to find something for MMS on the backend 
 ** hope to have 2-3 devices working with linux/ofono/postmarketos to test with 
 *** hammerhead 
 *** surnia (MSM8916 supports mainline but needs device support) 
 *** Alcatel Go Flip (4044W, MSM8909), will work on after surnia mainline is done 
 ** haven't even worked on 2G mediatek baseband/re lately so will tackle that FIRST before getting into 3G 

 * 10/31/2018 - rebuilt all NITB sources, configured DHCP, NTPD, got ip.access nano3g connected to nitb laptop and able to register phones on network. sms/calls don't work yet. Phones get kicked off periodically. 

 * 04/19/2017 - built all required projects with a few warnings and details 
 * TODO - take build notes and suggest changes in docs, fix warnings in builds? 
 * TODO - finish setting up and run the network 
 * TODO - test voice, text, data 
 * TODO - leverage fernly mediatek bootloader and various mediatek baseband sources to create 3G baseband, osmocom-bb? 
 * TODO - setup EC20 modules and test 

 h2. Code (can boot a simple firmware that only spits out a bit of data on the USB serial port on fernvale)
