CC1101: can't able to receive data over RX02-ASK module while transmitting over CC1101 module

Part Number: CC1101

Hello Sir/Madam,
I am using cc1101 module as a transmitter and ST-RX02-ASK module as receiver which supports Receiver Frequency: 315 / 433.92 MHZ ,Typical sensitivity: -105dBm ,Supply Current: 3.5mA and IF Frequency:1MHz .
I have below queriies,

1). Is cc1101 module will able to communicate with ST-RX02-ASK module? (beacuse i have checked it on esp8266 but they are not able to communicate)
2). If yes then what changes need to be done?

we are planning to use same module cc1101 for both the side but having question that will it work properly?  If yes then can you please provide the proof (ex. video or source code) that cc1101 modules will communicate properly without any issue.

Thanks and Regards,

Omkar

    Two modules will be able to communicate given the same modulation format, frequency, packet format. 

    If I understand the ST-RX02-ASK datasheet correctly, this module just give out a datastream when receiving data, with a maximum datarate of 3 kbps. The description of ST-RX02-ASK does not cover how you get the module to operate on the wanted frequency or if the module exist in two different versions, one for each frequency. 

    You are also writing that you use a CC1101 module. Do you have more details on exactly which module you are using?

    Hello TER,

    We are using CC1101 module which support all the frequencies(ex. 315/433/868/915MHZ).

    We have tried it with ST-RX02-ASK but it is not able to receive data.

    So now we want to use same module on both side (CC1101).

    But I need confirmation that we use the CC1101 both the side are they able to communicate with each other without any issue?

    I need the proof (ex. video or source code) that  CC1101 modules will communicate properly without any issue as we stuck for the production.

    Regards,

    Omkar

    Do you mean a module with CC1101 on or are you referring to CC1101 the chip when you write "We are using CC1101 module which support all the frequencies(ex. 315/433/868/915MHZ)."

    The reason I ask is that one PCB/ antenna will not be able to cover all frequencies band, a PCB/ antenna is normally designed only for one band.

    "I need the proof (ex. video or source code) that  CC1101 modules will communicate properly without any issue as we stuck for the production.":

    You have not specified anything about with datarate, modulation etc. If you in SmartRF Studio select the same setting both for RX and TX you will be able to communicate between two boards with CC1101. Also, you write that you are stuck in production, please provide more details. What is the register settings, could you provide a schematic for the CC1101 module you are using etc.
