May be off-topic. Yesterday I've turned off my Bangel2 programmatically, issuing Bangel.Off(); in dev console. The screen turned off.
But this morning the battery was completely drained.
I was playing with GPS development before turn off.
Can it be that I've turned off the main board, but GPS chip was left running? -

I do not have much experience with JavaScript (have quite a bit with Java).
It is weird issue from my perspective. If I assign an object's method call to event, it runs in empty object instance. All fields are empty. But if I wrap object's method into a function, and put into event, it runs ok. Is it normal?
Example:const O = { A:"", B:0, M : function(){ this.A = this.A + "*"; this.B = this.B + 1; print(this.A," - ", this.B); } }; function F(){ O.M(); } // uncomment one or another call and run //setInterval(O.M, 1000); // method M runs in empty object instance //setInterval(F, 1000); // method M runs in populated object instance
Output of direct method assignment
undefined* - NaN undefined** - NaN undefined*** - NaN
Output of wrapped method assignment
* - 1 ** - 2 *** - 3

yeah, I also was puzzled regarding this "$GPSTXT,01,01,02,MS=..." sentence. It looks like it is indicator how stale is AGPS data?
I doubt though it is that simple "basically checks if fifth field is less than 9 "
What are FUN_00037c4c and FUN_00037cbc ? the latter one calls iVar2=FUN_00037cbc(msg + iVar2). like it reads a char with some shift from the msg? weird. -
Yes, I also found couple of docs on web. Chinese ones and translated. Like Multimode_satellite_navigation_receiver_cn.pdf
Or this one http://wless.ru/files/GPS/Neoway/G7A/Neoway_G2_and_G7A_Commands_Manual_V1_0.pdfI use CAS commands from it.
Yes it is possible to turn on/off types of NMEA messages, change frequency of them, select constellations etc.
Regarding turning on/off types of NMEA messages (CAS03) the chip that is in Bangle2 is configured slightly different then it is documented in the docs I've found. It would be nice to find the doc for the actual chip/firmware.I am going to create some Setup GNSS app or at least an example in Wiki.
Also I am looking to try CASIC binary format instead of NMEA for logging, probably it will be more efficient from space and performance perspective.

I've read about Layout. Its capabilities are impressive!
But I still have a question. What would be faster, smaller and overall more efficient: Layout or direct Graphics calls?
Let say I am doing digital watch and update only the digits that are changing.Layout code is 14K, is it compacted when loaded into device?
Hi Gordon, I cannot find datasheet for SMA Q3. Do you have one?
If you have disassembled watch, did you see an antenna there?
