Hello Sailors! I developed some tools with Ant+
protocol, using nrf24ap2, dynastream usb stick, atmega mcu with arduino, samsung s5, timex sensors.
Now I'm trying to develop an ANT+ toh.

First of all: what Antplus is.
ANT+ is the wireless technology that allows your monitoring devices to talk to each other. Leading brands design ANT+ into top products to ensure that you get the data you want - when and where you want it. Fundamentally, ANT+ gives you the simplest, most expandable and most reliable user experience possible.
ANT+ stands for interoperability which means that ANT+ products from multiple brands work together. Plus, because devices are compatible, you can always add to or update your monitoring system.
ANT+ is a direct concurrent for Bluetooth in fitness devices world.
I choose it because of the easy configurations and low power condumption.

THere are three ways to do this:
1.Develop a bluetooth-ant+ bridge to include into toh: the bluetooth com port will be used from SIMULANT app.
2.Develop a pcb with I2c-uart bridge for talking directly with nrf24ap2 through SIMULANT app.
3.Develop a pcb with Arduino nano and nrf24ap2 with ant+ routines already embedded inside atmega firmware so the phone will read only data sensor without caring of handshaking, device searching, etc

At this moment I'm thinking the best way is to start from point #2.

I will update the next steps in this thread

what is ant+?

Edit:
google always haz the answer, but the ant site is not very clear and seems like a good plan to include this and the endgoal in your thread

ANT+ is a technology (owned by Garmin) that allows devices to communicate with each other. Its mostly used by (unsurprisingly) GPS/cycle computers/heart rate monitors. Would be a good fit for a TOH
