Bluetooth module

[nionata]

Get an MVP of a bluetooth module working that at a minimum can both scan and advertise. This is a sanity check to ensure we can use ble the way we plan.

• [x] Central manager scans for custom service #23
• [x] Peripheral manager advertises custom service #25
• [x] Transmit a single message #26
• [x] Add logic to the manager to auto switch between scan and advertise #35
• [x] Transmit a list of messages #35

I have been trying to integrate react-native-ble-manager with no success. The npm package has been installed as well as the corresponding ios pods. However, when running npm run ios I get the following build errors:

The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 15.0.99. (in target 'react-native-ble-manager' from project 'Pods')

I have checked the IPHONEOS_DEPLOYMENT_TARGET for the project and it is 12.0, so this doesn't make sense. I'm wondering if there is some build time injection of this lower value? When switching back to master the issue goes away and the app builds fine.

@paullegrand can you pull down nionata/ble-manager and see if you can repro the build error?

I tried installing react-native-ble-plx on a fresh branch from master. Same err message on build:

The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 15.0.99. (in target 'react-native-ble-plx' from project 'Pods')

Branch: nionata/ble-manager-2

We ended up going with the plx module. The errors were resolved by removing some garbage text packages that snuck in??

Scan for peripherals from the web

Peripheral module is working on an iphone. I was able to read a gatt characteristic via web bluetooth. @paullegrand was able to get the manager working yesterday.

Next step is to integrate the two

Choosing a GATT UUID

TLDR: To not conflict with a reserved UUID avoid XXXXXXXX-0000-1000-8000-00805F9B34FB

Huston we have lift off 🚀

Single message transmission is working with a few hiccups.

• The bluetooth mode has to be toggled in bluetooth/manager manually to Scan or Advertise. If both are toggled, the native bluetooth chip will schedule both tasks. This is confirmed by seeing device encounters in logs and the advertisement in web bluetooth.
• On device interaction in central, a error message prints and scanning stops
