@mfalkvidd thank you for quick reply, that was my copy/paste as my code is mess and i tried to paste as clean as i could hence this mistake, but i m using RFM69 radio. if rfm69 isnt lora radio then it mean range isn't going to be more then 15 to 20metter ? may be this is the problem? should i switch to rfm 95 for longer range? (i feel stupid now)

@mfalkvidd i was referring to un-shielded NRF24L01+PA-LNA radio modules. for me they never worked and even those ones worked had very power reception even in same room.

sorry i wasn't clear in my reply, in my country 868MHz is listed allowed frequency.

@zboblamont thank you, i think part of my problem might be allowed frequency is 868MHz as compare with mine 433MHz (school boy error) i have ordered 898MHz module and i will give them try.

i always had problem with that nrf pa lna, i suggest to get this one nRF24L01 PA LNA from Aliexpress
and thank me later. those type you have in your link are nothing but problem, i have few if anyone wants let me know pay me shipping and they are yours.

Thank you everyone for reply, i been searching around for antenna and how to test them and came across this guy.
#191 Optimizing Antennas using a cheap N1201SA VNA (Vector Impedance Analyzer), LoRa, Review – 16:29
— Andreas Spiess

i m thinking to buy one of these VNA as i m shooting in dark with antenna right now and no way of knowing what is going on under the hood, i dont mind spending more to get miniVNA Tiny+ but what you experts think?

Thank you for suggestion, is there any sketch for ping pong type communicate to do some testing?

i tried both radio types but can not get range more than 20m max in open air, tried coil type antenna, and all sorts things including capacitor from 10uf to 100uf, i m sure there is something missing in my setup i just dont know what it is, even nrf with pcb antenna perform better in open air, i wonder if any one even using rfm69 at all or it just me banging my head around.

@mfalkvidd thank you for quick reply, that was my copy/paste as my code is mess and i tried to paste as clean as i could hence this mistake, but i m using RFM69 radio. if rfm69 isnt lora radio then it mean range isn't going to be more then 15 to 20metter ? may be this is the problem? should i switch to rfm 95 for longer range?

Hi all,
First of all thank you for such great work. i been reading a lot on forum lately for different type of ideas and making my wireless communication work better or should i say reliably and today i plunge to register account and dear to ask question that might be very stupid or basic for all the black belt on this forum. so please go easy on me.

i have been testing nrf radio with esp8266 (gateway) and battery powered nodes but i can not get them to work through the solid walls so i decided to give try to RFM 433mhz radio but again failure.

so i m thinking i must be doing something wrong here, i watched tons of video on youtube about lora radio where people have achieved range in kilometres but i can not get range on these radio more than 20 meters, in example folder all examples are based on nrf radio. so if you can please guide me what i m doing wrong here or i m using wrong radio or wrong radio antenna. is there any sketch for gateway and for node to do some testing? also i have added 10uf and 100nf radio
