Excelent Plaform to develop Walkie with APRS and other functionalties

I write code for APRS and I'm developing also for this unit to have a one "does it all" and it comes very well into it. Great power with SA868, great flexibility with esp32s3 that enables to use It as walkie/handy, also send tones and afsk and also communicate with phones over BLE

Lack of Firmware Options

Virtually no interest in developing custom firmware for this product. The community seems to have abandoned this model. Factory firmware is extremely limited and clunky to use.

Barely works

Receiver is nearly deaf, I couldn't receive a single audio signal, couldn't even tune into 3/4th of the frequencies I know because the stock firmware is so bad. No de-bounce on the buttons is awful for navigating the menu.
Most of this is probably fixable with better software, but right now, the units are basically unusable.

Interesting Product

I am happy with the product but have two suggestions. 1) change to a battery holder that already has the spring in the holder. 2) The from (black plastic) gets loose and moves around quite a bit after handling.

Hi, thank you very much for your feedback and suggestions.
1. About the spring, we deliver the spring is to adapt the 18650 battery. The default battery holder is for 21700 batteries.
2. The black battery holder moving problem, it would be better if you can help to provide a picture, then we can confirm whether it is a welding problem, or the quality of the battery holder plastic problem.

Thank you for your patience.

Wonderfull device, but buggy

It is a great concept, but has some quirks that need to be addressed. If left off for a long period of time, it will drain the battery past the safe discharge limit, all the way down to zero volts. One of the units died while working and subsequent efforts to bring it back to life put it into a reboot loop. ESP32 chip had cold solder joints, now fixed, but now the chip gets very hot, making it unsafe to operate.
