It's driving me nuts. I have completely redone the code, and used the example in nimble_ota.c After succesfully transmitting data, I get error: E (72038) esp_encrypted_img: Magic Verification failed E (72038) NimBLE_BLE_OTA: Error in decryption: -1 This is my current swift code: func initPackets() {...

Also spend a few hours by looking into the android app (https://github.com/EspressifApps/esp-ble-ota-android/releases/tag/rc) and adding Sector_Index numbers and Packet_Seq numbers in my packages, by updating my iOS code. Like: https://components.espressif.com/components/espressif/ble_ota tells me. ...

Yes, I see. But shouldn't my code pass the decrypted code, instead of the encrypted code to esp_ota_write? Some pieces of my code to get a better idea of the current code. esp_decrypt_cfg_t cfg = {}; cfg.rsa_priv_key = rsa_private_pem_start; cfg.rsa_priv_key_len = rsa_private_pem_end - rsa_private_p...

Hi everyone, I've been grappling with this issue for several days now, and I'm at a loss. Previously, I had successfully implemented OTA updates using non-encrypted images with ESP-IDF/iOS. I am now transitioning to using encrypted images, which has proven quite complex. I've integrated the OTA BLE ...

By switching the mode to APSTA, I've noticed that the connection has become significantly more reliable. esp_wifi_set_mode(WIFI_MODE_APSTA); However, I still find that the range for ESP-NOW communication seems to be limited, perhaps to a maximum of about 8 meters. Is there a way to configure the set...

Hello everyone, I'm currently working on a project with multiple ESP32s communicating via ESP-NOW. I need some guidance regarding the consistent reception of sent messages, and I hope the community can assist me. Issue: In my setup, I have several ESP32s exchanging messages every 5 seconds. However,...

Fixed!

Hello, I'm in the process of transitioning from Arduino to ESP-IDF, and it has proven to be quite a challenge. I've dedicated the last couple of days to getting BLE up and running. I stumbled upon the gatt_server_service_table example and I'm attempting to comprehend its workings. Currently, I have ...
