Re: RePhone analog read problem

Running the adc_test sketch and connecting A3 (breakout E/1) with 2V8 (C/5) with GND the value goes down from 1023 to zero.
This worked in my case also when the display was connected (but not in use). The touch pad is a i2c device so you should be able to use it simultainiously with the ADC.

Re: RePhone analog read problem

Hi jianzhang.su, thank your for the advice. I tested the adc_test.ino script. Connecting A3 (breakout E/1) with 2V8 (C/5) or GND has no effect. First i tried the adc_test.ino script with the complete assembled RePhone. For a second test i connected the Xadow GSM+BLE only with the Xadow GSM Breakout....

Re: https_test test program not working

The scirpt waits for an input. You simply have to press a key on your keyboard.

I made a test with my thingspeak account.

I replaced the URL like this.
#define TEST_URL "http://api.thingspeak.com/update?key=Y O U R K E Y &field1=5"

It works fine and is very simple!

Re: (TECH) Unable to falsh Adrunio IDE firmware

I had the same problem but after several trials an errors now it works - no reason why. Maybe these advices help to avoid or overcome the problem: - install the drivers as admin. - be shure, that the battery has enough power. - run "\Arduino_IDE_for_RePhone-master\drivers\mtk\UninstallDriver.exe" to...
