I tryed to contact Dynastream but I had no so clear explanation... Here can be found the discussion ---> www.thisisant.com/.../ thanks

I'm sorry. You are correct. It seems they have made serialization firmware (ANT network processor application) for it. Maybe you can find something useful in tech resources here? I think you should contact Dynastream regarding application support, at thisisant.com.

Thanks Petter for your response, excuse me I add an answer below, could you help me? Thanks.

Hi, and thanks for response... so in attach there is a picture of the D52QD2M4IA module.

I bought one of it connected like following: The wiring I used is:

H202 -> TO ARDUINO PIN FOR RESET FUNCTION
H203 -> VCC
H204 -> GND
H206 -> TO ARDUINO PIN FOR SUSPEND FUNCTION
H207 -> TO ARDUINO PIN FOR SLEEP FUNCTION
H209 -> PORTSEL TO GND (ASYNC)
H210 -> BR2 TO VCC
H211 -> UART TX TO ARDUINO RX
H212 -> UART RX TO ARDUINO TX
H213 -> BR1 TO VCC
H214 -> BR3 TO VCC
H217 -> RTS TO ARDUINO INPUT PIN

BR1-2-3 to VCC = selection of 57600bps serial UART speed

When Arduino starts it execute this routines...

// module reset
void hardwareReset() {
[... some other code ...]
digitalWrite(RESET_PIN, LOW);
delay(5);
[... some other code ...]
hw_reset_count++;
delay(5);
digitalWrite(RESET_PIN, HIGH);
[... some other code ...]
}


// **************************************************************************************************
// * ANT Management Routines
// **************************************************************************************************
void antBegin() {
pinMode(SUSPEND_PIN, OUTPUT);
pinMode(SLEEP_PIN, OUTPUT);
pinMode(RESET_PIN, OUTPUT);
pinMode(RTS_PIN, INPUT);
[... some other code ...]
digitalWrite(RESET_PIN, HIGH);
digitalWrite(SUSPEND_PIN, HIGH);
digitalWrite(SLEEP_PIN, LOW);
//This should not be strictly necessary - the device should always come up by itself....
//But let's make sure we didn't miss the first RTS in a power-up race
hardwareReset();
}

It respond me so I assume that there is a firmware that can "drive" the ANT protocol or not? I do not download any kind of software in it...

How can I solve my issues?

My needs is to read as many as HRM data and pass thought Arduino to a PC application. Could you help me? Thanks.

You are sending commands over UART to the nRF52? What firmware are you running on the nRF52? We don't have an example for running a serialized application with the ANT SoftDevices, only BLE. The nRF24AP2 is only a connectivity IC, while the nRF52 is not, but can be.
