ESP8266 MQTT gateway radio problem

ferpando

Hello,
I created an MQTT gateway a few days ago and a node to check communication.
I'm on 2.1.1 and everything seems to work fine most of the time.

But sometimes, when powering up the node, I get lots of fail massages.

The gateway receives messages from the node, but for some reason the don't understand each other.

Here is the log from the node:

I tried the log parser but I don't see where is the problem.

I'd appreciate any help.
Thanks in advance

Try a bigger capacitor on the gateway radio or try to move the node closer to the gateway to see if you see any change

ferpando

Tried all sorts of things.
Also tried the module with antenna and the one without..
The problem is random.

When it happens, I see the node sending data, and I see the gateway receiving it realtime, but the do not connect.
That's what I don't understand.

gohan

if you swap radio modules, do you still have the exact same problem?

ferpando

yes.. more or less the same

gohan

I had similar problem with rfm69 radios. I am waiting for other modules to arrive

ferpando

Thank you.
I'll keep trying some other things..

Hello, it looks like a "classic" radio link quality problem.
What antenna version of the radio module did you try ? Did you use it with RF24_PA_MAX define to have maximum power ? And in that case did it have a sufficient power supply ?

I just tried a PA LNA module from CDEByte with an external antenna and even in the worst locations at the two ends of my appartment it's not losing any packet, while before I sometimes had lost packets and sensors not reporting for some time. I also had poor results with the "classic" version of the PA LNA module with antenna. So my suggestion is to try with a better pa lna module on your gateway. For example this one: https://www.aliexpress.com/store/product/E01-ML01DP5-Ebyte-2-4GHz-20dBm-2100m-nRF24L01-SPI-Wireless-transceiver-module/2077046_32638720689.html

Thank you.
I'll make some tests if I can find one
