Hey iam using Bc66 module with esp32 . iam using the transistor part as level shifter iam trying to set Baud rate of 4600 when i try to communicate with the BC66 With continuous AT command there is no ok reply from . I checked the voltage at my esp side it is 1.5 nealry half of the voltage since iam communicating but when i checked the BC66 side iam getting 1.8v where i should get 0.9V means iam getting continuous 1.8v on the pin RX of Bc66 . how to slove this . or does my module is in anyother mode . iam getting VDD_EXT as 1.8V and sim_vdd as 1.8V
Is AT execution normal at baud rate 9600?
Hello ,
Thanks for the reply ,
The problem is sloved the issue is from my side . in firmware i have swapped the pin of RX and TX after correcting that it worked ,
Thanks
