We have working products based on q2400, q2406, q2501… But while experimenting with q24 Classic and Plus series we found that it cannot correctly measure the battery voltage level.
For example, we have 4 V on VBATT, but the q24 module switches off with +WBCI:0. With extended WBCI information it shows +WBCI:3,3200…
Q2400 on the same board with the same AT command shows +WBCI:3,4000.
So it seems that new q24 modules interpret VBATT voltage wrong. Can anybody help with this problem?
