Also the BQ5102X EVM GUI may be help in debugging the problem.

Hello
The BQ51020 (WPC) or BQ51021(WPC) are better alternatives to the BQ51221(WPC+PMA). They have similar pin out and will fit the TIDA-00243 form factor. The 020 and 021 will support WPC only. Units have been certified to WPC 1.2 standard.
Hello
The BQ51021 has I2C interface and the option to send data to the transmitter. For this approach you will also need an transmitter that can support this function. The BQ500212A has I2C.
Sorry do not have info on coil that will act as NFC and…
Other Parts Discussed in Thread: BQ25896 , BQ51021 Dear BMS team,

thanks

Son,
Are you interested in the receiver or transmitter displaying charge status? The transmitter (bq500511A) would need to get that information from the receiver. If it's a display on the phone, then that information does not need to go to the transmitter…
Hi Janith
For data transfer RX to TX it may be possible to used the Proprietary Packet option of the bq51021 Receiver to send info to bq500215 TX. This would require I2C communications with both RX and TX.
