Clarification on capabilities of nRF51822 devices

Post by jacobniman_gm »

Intention- For my final goal, I want multiple bluetooth "devices" to be wired together to a single Arduino. These devices should then be able to ping a single bluetooth peripheral device, not establishing any bluetooth connection just retrieving the RSSI and MAC address of the peripheral device through one ping

I already have the peripherals i want to ping in my inventory.

I had ordered the following "Adafruit Bluefruit LE UART Friend" ( https://www.adafruit.com/product/2633 ) with the intention of using these as the devices doing the pinging of my peripheral devices and sending the information back to the master arduino, however after viewing the API I don't see a way of doing this with these chips. I was going to order something else when I came across a different board ( https://www.adafruit.com/product/2269 ) that uses the same bluetooth chip that the ones I have used, yet it has support to accomplish my end goals (but not the proper hardware configuration)

I just want to check if I missed something and if I can do it with that device, else I should get the device listed in the FAQ of the original device ( https://learn.adafruit.com/bluefruit-nr ... troduction )

Thank you, ~Jake

The nRF51 hardware is capable of operating as a BLE central device, but the central software stack is too large to fit in the available program space of most microcontrollers. Our nRF51 libraries only work as peripherals.

We've just released an nRF52 Feather that does work as a central:

It can only pair with one device at a time right now, but should be able to read advertising packets from any number of peripherals.
