change(ESP_NOW_Serial): No teardown on retry limit

[ClockeNessMnstr]

Description of Change

After max retries is met once the ESP_NOW_Serial_Class performs "end()" which removes the peer from ESP_NOW. Further messages to and from ESP_NOW_Serial are not received or sent. Peer should stay in ESP_NOW to re-establish connection even with data loss. This change will "retry and drop" the data piece by piece instead of aborting the connection. Description of Change

ESP_NOW_Serial "Peer" will not remove itself from ESP_NOW_Peer list when data sent is not received by a peer. ESP_NOW_Serial::end() is still called when ESP_NOW::send() fails Tests scenarios

Tests scenarios

Tested on a pair of M5Stack Stamp ESP32-C3.
Confirmed that transmission is able to continue after: disconnecting the Receiving module from power.
Attempting to send data.
Restoring power to Receiving module.

Previously, transmission halts as the cleanup/teardown in ESP_NOW_Serial::end() is triggered.

I did not create an issue for this.
Issue was NowSerial had to be re-initialized essentially for every byte without knowing if the peer was present/restored.

Workaround was to use broadcast address for TX and a separate ESP_NOW_Serial peer with MAC address for RX.
