LoRa sender not working

[lucas-figueiredo-m]

Hello everyone! Yesterday I had cloned the repo, followed the instructions on the README and created 2 esp32 projects on my PC: one for the sender and another for the receiver. But it seems that the sender code isn't working.

Triyng to debug the code, I have inserted some printf functions inside the lora_send_packet function on lora.c . I have found that the code isn't escaping the following
while loop:

while((lora_read_reg(REG_IRQ_FLAGS) & IRQ_TX_DONE_MASK) == 0) { vTaskDelay(2); printf("Waiting\n"); }

Do you have faced the same problem? Are those regAddresses right? I think that I'm doing something wrong, but I can't see what.

For instance: I'm using the SX1278 chip ( the RA-01 module). It can only uses 433MHz as carrier for the transmission

I currently have the same issue. Have been able to solve this? I'm starting to investigate.

Same here, tested with SX1278 and LoPy board. It gets stuck in the same loop. Any news about this?

Working now. For me it was the RST pin. Connected to EN and worked perfectly afterwards.

I have simmillar issue. I normally find this issue when turning on my device for the first time, LoRa module will get stuck in this while loop for some time (sometimes around a minute or so) and then will start working without any issues as normal. I have created a seperate issue for this:
#26

I dont see how RST pin can have anything to do with this. Did you investigate it further and found anything else?
