- Topic: BLE pairing on AndroidYou Reply: By the way, should I use a logic converter? I am using a generic one but i check the schematic of BLUNO and compared it with the BLE LINK and the way I see it is that in BLUNO the RX,TX of the ATMEGA328 is directly connected with 4.7Kohm Resistor to the RX,TX of the CC2540F256(main chip of the BLE LINK).
I did not see any circuit for logic converter, or I just missed it in the schematic.
here are the link of the schematic
