Tool/software:
Hi team,
We originally used the CC2530+CC2591 development board we bought, which can be used for networking and communication.
In the new version, we replaced the amplifier chip with CC2592 and used the officially recommended circuit: www.ti.com/.../CC2530-CC2592EM-RD
In the software, I have also made modifications to the corresponding en pin, OBSSEL4 -> OBSSEL0
The original circuit diagram and the new circuit diagram differ only in the en pin.
Original circuit pins: P1_1->PA-IN, P1_4 -> LAN_EN, P0_7 -> HGM.
Current circuit pins: P1_1->PA-IN, P1_0 -> LAN_EN, P0_7 -> HGM.
Then, they won't be able to form a network. If the BIAS resistor of CC2592 is removed to prevent it from working properly, the network will work again, but the distance will be very close, around 10CM.
If CC2592 is added, it will be completely impossible to network, which is strange. I don't know what the reason is.
Thanks & Best regards,
Jiahui
Hi Jiahui,
Please make sure that you are defining HAL_PA_LNA_CC2592 and have the correct board initialization. You can try to view the PA_EN/LNA_EN/HGM lines with an oscilloscope for further insight, and provide your Z-Stack version.
