One of my new TBEAMs (node id 0x1c) has an interesting problem:

After any transmit it gets stuck printing this:
Can not send yet, busyTx

The root cause (confirmed with logic analyzer is some sort of hardware failure in the radio chip module) - it never asserts DIO0 to the main CPU. So it seems (unsurprisingly) TTGO has some QA problems ;-).

Eventually it would be nice to notice this fa

Display of Map-path in Gui-list
I use paths for the maps as short as possible, so even the first characters of the filename is displayed in Gui.
By trials with navit-apk_0.5.4 I found, that these paths are no more accessible for navit. I succeeded finally with path like
"/storage/0403-0201/Android/data/org.navitproject.navit/files/SW_Paris_Grosseto.bin".
The use of this path is no problem.

I am trying to support Raspberry Pi 3. The linux driver code has the 7100 but not the 7000 listed.
When I try to compile on raspberry - jesse it gives error:
make[1]: *** /lib/modules/4.9.59-v7+/build: No such file or directory. Stop.

The Simcom site says there are both linux and android drivers for the 7000, but I can not find them.

The module works perfectly with Arduino! Thanks.
