Adafruit packet radio RFM69 solutions

Post by ValenceElectrons »

The product descriptions emphasize “… All radios … can only talk to radios of the same part number.“ It is unclear whether this means the Adafruit product part-number or the part-number of the imbedded radio chip itself. Please confirm whether the Breakout can talk to the “equivalent” Bonnet:
Adafruit RFM69HCW Transceiver Radio Breakout (915 MHz) (Prod 3070)
Adafruit RFM69HCW Transceiver Radio Bonnet (915 MHz) (Prod 4072)
I would like to develop a project where a Pico based Breakout talks to a PiZero based Bonnet.

Also, it is unclear to me from the tutorials whether the radio Breakout modules (and the CircuitPython libraries) are compatible with the Pico? I’ve seen some forum discussions but they did not explicitly describe the hardware combination (radio product and Pi) being used.

Thanks!

Any of the RFM69 products can communicate with any other RFM69 product as long as they are of the same frequency. A 433 MHz radio will not work with a 915 MHz radio. A Pico with RFM69 breakout can communicate with a Raspberry Pi Zero with an RFM69 Bonnet as long as their frequencies match.
The warning pertains to mixing RM69 and RFM9x products. They use different communication protocols and are not compatible with each other.

The adafruit_rfm69 CircuitPython library will work on the Pico and can also be run on the Raspberry Pi with “Blinka”. See this guide https://learn.adafruit.com/circuitpytho ... spberry-pi. On the Pico you will have to explicitly configure the pins for the SPI interface (MISO.MOSI,SCLK) since there are not predefined defaults as there are for many boards. This is described here https://learn.adafruit.com/getting-star ... on/pinouts.


Just to be clear, I do not represent Adafruit. I’m just trying to help.

Thank you! I have ordered the breakout and will forge ahead to the next level of investigation. Thank you especially for the pin-out link.
