Hi, I have a big question in hardware design with SX1276 now. The datasheet show me that the RXTX/RF_MOD’s pin description is Rx/Tx switch control and high is Tx. Unfortunately, to get better RF performance, logic is contrary to the antenna switch’s datasheet, so when SX1276 is transmitting signal, Rx path is connect.
I try to use a triode to change the state of the switch, but it doesn’t work, so I have no idea to solve this problem.
Is there some solutions with software? Can I change RXTX/RF_MOD’s setting by change the code?
Thanks for your help. If you need more information about this problem, please contact me.
Best regards!
Xue.
