Can somebody suggest me the 10 meter range 2.4ghz RF ic's for my project. NRF24 having more than 100 meter range. I want only 10meter range with in built antenna.

Hc05 bluetooth modules are costing high india. Need low range RF ic's with same pin outs like nrf24

 

Just reduce power

 

how to reduce the power. Pls suggest

 

nRF24L01+ has four power levels:

1. 0dBm
2. -6dBm
3. -12dBm
4. -18dBm

 

Just curious, whay to substitute wonderful tablet at cost 0,99 $ per piece with who knows what being genuinely worser?? Just set the output level less and go on!
