Watch connection to two bluetooth transmitter modules (ARDUINO)

Hello, I am not a programming expert.

I would like to connect two bluetooth transmitters managed by an arduino to a watch.

The objective is to make the watch vibrate when receiving information from the arduino. this application responds to a problem around football, for which I can not say too much on this forum.

If an experienced developer wishes to accompany me on this project, do not need to contact me: [email protected]

thank you,

have a good day;

The first thing you probably want to think about is the BLE range on both the watch and arduino. Both have limited range, and when you mention football, that could be a big issue. Would it be more than say 20 feet?

In CIQ BLE, you are limited to 3 services as a max. Multiple BLE devices should be possible, but still only 3 services total.

Thanks for your return, Currently I carried out the test with my phone (by means of message) the range is sufficient. I have already connected two 5.0 transceiver modules the range was also sufficient. On the ground, there are no obstacles. On a watch it is not possible to go through radio transmission?

For the number of devices, 2 devices is sufficient.

Try with this app on your garmin:

First of all you can see if the sensors are seen by the watch and for how far. The current version is only looking for advertisement, but I'm working on one that allows an attempt to connect to a device (only one at a time)
