Which Bluetooth LE board to buy: UART or SPI

by nonuniform on Fri Apr 09, 2021 2:20 pm

I'm building my own portable GPS receiver that will connect to my (wifi-only) ipad via bluetooth. So...

I'm buying this GPS module:
https://www.adafruit.com/product/746

And I want to hook up its data out to a Bluetooth module.
https://www.adafruit.com/product/2633 (SPI version)

I plan to add a battery to power it.

Should I use SPI or the UART bluetooth module?

Thanks!

I would use the UART bluetooth module as we have more BLE UART examples and the Ultimate GPS module is UART.

Have you seen a working setup using Ultimate GPS + BLE Friend? I didn't see a guide of ours on this topic.

I haven't seen anyone do this with Ultimate GPS + BLE Friend, but I've seen examples of projects using similar hardware. Not sure if there's any reason it won't work using this hardware, but, I guess I'm interested in a building something new that I need.
