Thank you for your message!
Could you let me know how to set 920MHZ ?
By the way, Specification metal IC Tag of mine is "Up to 4.2M - (US) 902-928MHz, on metal"
Web page shows
"the transmission power of 100mW can reach the effective distance of more than 1.5M."
But my JRD-4035 effective distance is 0.4M
If possible , could you let me know why JRD-4035 is low performance ?
Specifications of Output power range is 18-26 dBm
Could you let me know how to adjust max output power 26 dBm?
I found Arduino IDE sample
// UHF_RFID set UHF_RFID设置
Does 2600 mean 26dBm ?
If i set "RFID.Set_transmission_Power(3000) ,Is output power 30 dBm ?
Dear Feimue san
I added "_Noreturn" command on ahead of original sketch as follows
_Noreturn UBYTE UHF_RFID::Set_the_communication_baud_rate(UWORD Pow)
Result : "UHF-RFID-JRD4035" can get data from IC Tag.

Dear felmue san,
Thank you for your kindly reply!!
I will try based on your advice from now on !
UBYTE UHF_RFID::Set_the_communication_baud_rate(UWORD Pow)
ToHex(Pow, 5, 6);
If possible ,could you help me how to solve this problem ?
I use Atom lite esp32 ,therefore my Arduino IDE setting is as follows
Board :ESP32 Pico Kit
Upload speed :115200
If 10 Metal Tags are placed around the JRD-4035, Can JRD-4035 get the information of MetalTag which is the closest to JRD-4035?
If JRD-4035 can , What parameters does the JRD-4035 need to read ? For example, is it RSSI?
Thank you very much for your kindly reply!
Is function of UHF-RFID-JRD-4035 only reading IC tag information ?
Is there function of writing information on IC tag ?
If there is not function of writing information on IC tag , could let me know the writing device that works with Arduino/Atom lite esp32 ?
Thank you very much for your quickly reply!!
I will continue to investigate it by myself .
If i find additional information, i will describe on this forum.
