Reading sensor data from the GPIO pins via bluetooth in iOS app

elihar

Hi, 

I'm new to electronics, but know a bit in iOS development. I'd like to connect 2pin sensors to the metawear, but don't know how to read the values of the sensors in my iOS app. How can I send the sensor values through Bluetooth. and will the reading be live??

Use the gpio class:

Reading it worked fine. However, I connected 4 sensors that are connected to the analog pins 0,1,2,3 and using the provided method, but had an issue:

- (void)readAnalogPin:(uint8_t)pinNumber usingOptions:(uint8_t)option withHandler:(MBLDecimalNumberHandler)handler;

So I wanted to read all 4 pins at the same time, but it would ONLY read the pin that was in the first method to be called.

Thanks for bringing up the issue, this will be fixed in the next iOS API release.  That release should be out by end of week.

When will the new iOS API be released. Looking forward to it.

Thanks
