Problem with join to TTN US915

[lyakh-m]

Hello! I use WiFi LoRa 32 (V2). I modified the OTAA_OLED example for the US 915 range (Comissioning.h: LORAWAN_DEVICE_EUI, LORAWAN_APPLICATION_EUI, LORAWAN_APPLICATION_KEY; LoRaMac-definitions.h: USE_BAND_915; and scetch for correct LICENSE). However, I see only periodic registration (activation request) in the TTN network, and I do not observe data (Payload and answer) transmission at all. What could be the problem?
I see requests going through the router like:
{"rxpk": [
{ "tmst":443640556,
"chan":3,
"rfch":0,
"freq":904.500000,
"stat":1,
"modu":"LORA",
"datr":"SF10BW125",
"codr":"4/5",
"lsnr":-6.8,
"rssi":-95,
"size":12,
"data":"QJokAiaA6UW/fzxl"}
]}

{"txpk":
{"imme":false,
"tmst":444640556,
"freq":925.1,
"rfch":0,
"powe":20,
"modu":"LORA",
"datr":"SF10BW500",
"codr":"4/5",
"ipol":true,
"size":22,
"ncrc":true,
"data":"YJokAiaKfgADQAIAcQMFAP8BDe/yFQ=="}
}

UPD 12/31/2019. I also tried using the "CubeCell Board" and it works fine.
Is it possible to remake the library for "WiFi LoRa 32 (V2)" so that it looks like a library for the "CubeCell Board"? Because the library for the "CubeCell Board" has the ability to configure from the menu, which greatly reduces the possibility of errors when working with it.
I tried to figure out the code and structure it similarly to the library for the "CubeCell Board", but it turned out to be unexpectedly difficult for me. @Heltec-Aaron-Lee

I'm having a similar issue while working with ChirpStack RAK gateway and I use WiFi LoRa 32 (V2).

Similar problem here. I can't see the upload on my application with 915 version.

I'm using the RAK 7258 and had to change the Frequency Sub-Band see http://community.heltec.cn/t/solved-wifi-lora-32-v2-ttn-joining-trouble/670
Now the joins are sent and received by the ChirpStack server. ChirpStack sends a JoinAccept, the RAK transmits but the device doesn't seem to acknowledge it.
