Just one: <unrznbl@unreasonablefarm.org>.

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.

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

Details¶

• debian linux
• EC20 module
• iPhone 4

  - 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.
