Ble-link and serial port monitor communication. No answer
Account cancelled 2015-04-18 05:31:03 2503 Views1 Replies Hello!
I bought Ble-Link and tried to connect it with arduino and serial port monitor from Arduino IDE. I've done everything what is included in instruction "Configure the BLE through AT command". But when I typed '+++' there was no answer, nothing appeared. My connections between Ble-Link and Arduino UNO:
1) Arduino's TX connected to the Ble-Link RX via 1.2 kOhm resistor. Ble-Link Rx is also connected to GND via 2.4 kOhm resistor. (It is kind of voltage divider)
2) Arduino's RX connected to the Ble-Link TX
3) Of course Ble - Link is properly connected to the 3.3 V power supply.
Can Anyone please help me? Have I forgot about something? What Can I do more?

which ble product you are using?
generally speaking , for example_ bluno, just connect it with computer via USB cable, open the IDE monitor, choosing the "No line ending"(①) and 115200 baud（②）,and send "+++" you will see the reply"ok",then choose "Both NL & CR",you will have the right to use the AT command.
