stm32bluepill-mynewt-sensor's Issues

Proper error handling

stm32bluepill-mynewt-sensor/src/send_coap.rs

Lines 19 to 23 in f51e078

 /// Also perform WiFi Geolocation if it is enabled. Return 0 if successful. 

 pub fn start_network_task() -> i32 { 

 console_print(b"start_network_task\n"); 

 0 

 }

Immediatly as I saw the video in the medium post I shuddered.

Do proper error handling in Rust!

Don't return ints to indicate errors or failures, use Result<(), ErrorType> instead. This is just one place, but everywhere where you have those ghastly assert!(rc == 0) things, throw them away and burn them! Either use unwrap, or better expect.
