Re: Feather 32u Bluefruit COM Possibilities

Try adding this to the beginning of your setup() function: while ( ! Serial ) { delay( 1 ); } It takes a few milliseconds for the ATmega32u4 to establish a USB connection with the computer, and the Serial interface is null until that happens. Calls to Serial.print() fail silently if there's no worki...

Thanks! Was that step listed somewhere and I missed it? Or is it just assumed to be obvious? I’m new at this...

Re: Feather 32u Bluefruit COM Possibilities

The previous suggestion worked, thanks! The next error I am having with the Adafruit Feather 32u4 Bluefruit LE module is the following: there are quite a few Serial.print statements that are not being printed on the Serial Port. My code does instantiate some objects for ...

Re: Adding a pin code to Bluefruit UART Friend?

It is closed source due to Nordic early restricted license. If you are willing to mod, perhaps consider to switch to bluefruit nrf52 series. It is fully open source and is in active development, we will eventually add PIN support to nrf52 in the future

Re: nRF52840 Express not found on iOS Bluefruit app

Since the example sketch wait for Serial to connect before running.

Code: Select all | TOGGLE FULL SIZE
While (!Serial) delay(10);


Remove that and you are good to go.

Re: nRF52840 Express not found on iOS Bluefruit app

I also apparently can't figure out how to charge the 3.7V 400mAh battery that goes with it. I plug the battery into the Feather, then plug the Feather into a USB port or charger, and nothing happens. I'm assuming that the CHG led on the Feather should light up when it's charging, since that's what t...

Re: Feather 32u Bluefruit COM Possibilities

It sounds like the Feather's USB firmware is crashing, which can happen sometimes. The ATmega32u4 handles USB internally, so its USB interface is part of the bootloader. High-speed USB ports start the device recognition process with a burst of data about 30x faster than the CPU clock. That can make ...

nRF52840 Express not found on iOS Bluefruit app

I tried to connect an nRF52840 Express to my iPhone, but it doesn't show in the Adafruit app. It sees other BT devices just fine. This is powering the Feather via a USB charger. I was able to have some success plugging the Feather into my Mac, launching the Arduino app (after installing everything p...

Re: Adding a pin code to Bluefruit UART Friend?

Is anyone able to help?

I'm guessing this would require changing the firmware of the BLE UART Friend itself.
Can anyone advise whether this firmware was developed in the Arduino ecosystem and possibly be available for me to modify? Or is it proprietary to Adafruit and closed off?

Re: Feather 32u4 bluefruit with GPS wing and IMU BLO055 I2C

Appreciate the breakdown on the signals. I cut down on the code to more of the basics with just the IMU and GPS. //Status- GPS not working with IMU //Suspect lines (GPS works with these commented out): // imu::Vector<3> gyroscope = bno.getVector(Adafruit_BNO055::VECTOR_GYROSCOPE); //With these comme...
