Bluefruit EZ-Link v1.1

Post by jjdeprisco »

Is the Bluefruit EZ-Link v1.1 still supported?

Trying to get some example sketches working with this old board from my inventory. Using an Arduino Uno R3. My circuit consists of only the shield plugged into the Arduino.

Adafruit Bluefruit AT Command Example
-------------------------------------
Initialising the Bluefruit LE module: OK!
Performing a factory reset:
AT+FACTORYRESET

<- Couldn't factory reset

Checked the forum, but didn't see any actual solution to this issue. Also no Youtube videos on the topic.

Using latest library.

Here's my code:

Code: Select all

// If you are using the Bluefruit LE Shield then you have an SPI-connected NRF51822 module.
// You can use this with Atmega328 (Arduino UNO or compatible), ATmega32u4 (Arduino Leonardo, compatible) or ATSAMD21
// (Arduino Zero, compatible) and possibly others.
// Your pinouts are Hardware SPI, CS = 8, IRQ = 7, RST = 4

    APPLICATION SETTINGS

? ? FACTORYRESET_ENABLE? ?  Perform a factory reset when running this sketch
? ?
? ?                         Enabling this will put your Bluefruit LE module
                            in a 'known good' state and clear any config
                            data set in previous sketches or projects, so
? ?                         running this at least once is a good idea.
? ?
? ?                         When deploying your project, however, you will
                            want to disable factory reset by setting this
                            value to 0.? If you are making changes to your
? ?                         Bluefruit LE device via AT commands, and those
                            changes aren't persisting across resets, this
                            is the reason why.? Factory reset will erase
                            the non-volatile memory where config data is
                            stored, setting it back to factory default
                            values.
? ? ? ?
? ?                         Some sketches that require you to bond to a
                            central device (HID mouse, keyboard, etc.)
                            won't work at all with this feature enabled
                            since the factory reset will clear all of the
                            bonding data stored on the chip, meaning the
                            central device won't be able to reconnect.
