@igrr
you can run the same from an SD card right now by the way

@chadouming
Ok, so that bootloader thing, it sounds amazing

@ficeto
I got my DSO yesterday and gotto look at some I2C pulses last night
the best pullup seems to be the 1K resistor
gave the closest to sqware pulses
today I plan to see why the ssd13.. fails when lots is going on

@igrr
which model did you get?
ficeto
@ficeto
DQ5202 ... they all the same... :D
this one is the 200MHz version

I can have access to a professionnal oscilloscope if you need test to be made

@chadouming we would need it if someone wants to investigate the radio. Which would be really cool...

i have access to an network analyzer at work, if some to test with tell me.

yeah :) mine is a shitty chineese DSO that I imagine costs a fraction of what those cost
unfortuantelly I have no clue how to use network analizer..
Markus
@Links2004
in basic it shows the raw "data" of the frequencies in the air. like an oscilloscope for radio.
ficeto
@ficeto
a good use for it is to see what power actually comes out of our modules
Markus
@Links2004
yes for example
ficeto
@ficeto
with the different antennas and settings
as we are not yet managing those
i saw a youtube video with a guy that had 300+ meters range with the trace antennas
Markus
@Links2004
free line?
ficeto
@ficeto
yup
Markus
@Links2004
and may not in the city to many noise therer
ficeto
@ficeto
netgear router on the other end
they were on a highway
it was rural but not that much
the other amazing thing is that he used an antenna from a router on another module
and got close to 500 meters
and using a directional mimo adapter, he got 3km +!
I can fly my RC things with that range no problem
Markus
@Links2004
as long no other 2,4Ghz stuff is there it is possible, but most of the time there is to many noise there.
unless you go to the Country.
ficeto
@ficeto
if the ESP really outputs 20dB, my FrSky gear outputs the same...
we all use 2.4 gear for RC :)
slightly different freqs
if there is any 2.4GHz noise, it's coming from other RC guys and the WiFi will be off of that
so might just work :D
Markus
@Links2004
next week i have holidays but after that i can check the ESP12 module output :) may the order ESP7 also be there then i can hook an antenna there.
ficeto
@ficeto
beter try esp-201
it does not have an integrated antenna
i imagine that would change things
well... you can cut the trace to the chip antenna and get the same result
Markus
@Links2004
the ESP-07 has an chip antenna and an connector the chip antenna an be solderer easy :)
ficeto
@ficeto
yeah I have those
wonder if the left over trace would matter
maybe unsolder the cap
Markus
@Links2004
yes shut be better
ficeto
@ficeto
good time to check if wifi would crap the PWM
