WiFiClass::status() doesn't return WL_NO_SHIELD when shield is missing #22
Description
On my Arduino UNO board in a pristine state, with the WiFi101 shield not connected, the following program just hangs in that status() call. I've tried it with both versions 0.6 and 0.5 of the library.
I've tracked the hanging to m2m_wifi_init() -> nm_drv_init() -> wait_for_firmware_start(). This is probably expected, but I guess the question is how come nm_drv_init() does't fail earlier (in nm_bus_iface_init()?).
This has tripped me because the 101 shield I got was not particularly easy to plug in at first.
#include <WiFi101.h>
void setup() {
Serial.begin(9600);
while (!Serial) { }
Serial.println("init");
WiFi.status();
Serial.println("why don't I get here?");
}
