Gateway MQTT on raspberry PI 4

[martim]

Hi,

I have moved my gateway from raspberry 3B to 4. But I have problems with receiving/transmitting. It is very unstable, sometimes it works sometimes not.

What I have done so far:

• made sure that the power on the RP. So I have ordered original RP power supply with 5V/3A
• took voltage from the NRF24 from 5 volts instead 3.3 and included a regulator MP1703 to go to 3.3 volts again
• check the wiring and connections
• the NRF has already cap of 4.7 uF on the plus/min
• I have used the 2.4.0-alpha version and recompiled the gateway with #define MY_RF24_PA_LEVEL (RF24_PA_MAX) (I also tried the other options)

So, anyone else is using RP 4 and maybe can give me some tips? The RP is connected to an SSD drive and use Zigbee and ZWave adapters (on extension cord)

Hopefully, someone can help me because I am frustrated :)
