I would like in the future to connect two arduinos through both bluetooth modules in order to send and receive message each one from the other one. When i connect to bluefruit bluetooth module from my phone program says UART CAPABLE but when i try to see message "Comunicando" in terminal of Adafruit app, this says Uart protocol can not be initialized.

I installed Adafruit Bluefruit LE Connect app in my phone.īlue led of CONN in bluetooth module is blinking (it is assumed that is sending message) as same time that RX in arduino is blinking. I plugged pin 0 (TX) from arduino uno to RXI of bluefruit module, pin 1 (RX) from arduino to TXI of bluefruit module.

i think for now we should document this as an unexpected consequence of the way trinket m0 is set up.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. oi yeah trinket is a very odd case because i fit all the pins on a dual sercom, so you could have either 2 sercoms for i2c/usart or one for a full SPI. When you post, please add #CircuitPython2022 and email to let us know about your post so we can blog it up here. for address in i2c.scan (): print ('- I2C device found at address: s. i2c I2C (1) Scan for I2C slaves connected to the interface and print their address. (Code pasted below) from machine import I2C Instantiate an I2C peripheral.
Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. But when I use the exact same code with the xbee connected to the trinket m0, the xbee cannot find any devices.
Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022.
