React Native module that support for SUNMI mobile printer devices.
I validate it with GMS enable and developable SUNMI V2 PRO and SUNMI V2s as follows. Though I do not have other devices, users report to work with V1s and V2.
| Android | SUNMI OS | firmware | storage | memory | NFC | |
|---|---|---|---|---|---|---|
| SUNMI V2 PRO | 7.1 | 3.6.23 | 754 | 16 GB | 2 GB | enable |
| SUNMI V2 PRO (foodpanda) | 7.1 | 1.0.33 | 138 | 8 GB | 1 GB | disable |
| SUNMI V2s | 11 | 3.0.11 | 242 | 32 GB | 3 GB | enable |
